Leandro Trossard claims Celtic caused “chaos” after Besiktas defeat.

Beşiktaş forward Leandro Trossard believes his team deserved to take at least a point from their Europa League meeting with Celtic, despite suffering a dramatic 3-2 defeat at Celtic Park. The former Arsenal player admitted that a period of “chaos” contributed to his side’s downfall as the Scottish club fought back to secure their first victory in the competition this season.

The visitors had looked capable of leaving Glasgow with a positive result after producing an encouraging performance, particularly during the opening half. However, defensive mistakes and Celtic’s improved attacking display after the break ultimately proved costly for the Turkish side.

Martin O’Neill’s substitutions played a decisive role in changing the direction of the match, with Callum Osmand and Camilo Durán making significant contributions after coming off the bench. Both players found the net as Celtic recovered from falling behind to claim all three points in an entertaining encounter.

Trossard, who joined Beşiktaş from Arsenal during the summer for a reported fee of £15.3 million, was left disappointed with the outcome. Speaking to TNT Sports after the final whistle, the Belgian explained why he felt his team had done enough to deserve something from the match.

Trossard believes Beşiktaş deserved more

The first half had offered little in the way of clear-cut opportunities, although Beşiktaş appeared to enjoy the better periods of possession. Trossard managed to test Celtic goalkeeper Sam Johnstone with an effort that required a good save, but the assistant referee subsequently raised the offside flag.

Despite failing to score before the interval, the Turkish visitors were encouraged by their performance and believed they had controlled much of the opening 45 minutes.

Trossard made that point clear when assessing the match, insisting that Beşiktaş had been the stronger team during the first half.

He said: “We controlled the first half especially, we were the better team. Then we made a mistake in the second half, we gave the goals away too easily, I think. Then it was a bit of chaos for us.”

His comments reflected the frustration within the Beşiktaş camp after watching their promising performance turn into a disappointing result.

The Belgian also acknowledged that his team needed to improve their decision-making and attacking efficiency, particularly when opportunities arose to threaten Celtic on the counterattack.

He believes the Turkish side have repeatedly failed to make the most of those situations in recent matches, something that can become particularly damaging when facing opponents at European level.

“We need to be better because I think in general we played better than them, but we need to take our chances as well,” Trossard added.

“Lately it’s been too many times for us where we’re not sharp enough on counterattacks. Then on this level you get punished, exactly today, that’s what happened again.”

For Trossard, the biggest disappointment was that Beşiktaş failed to turn their periods of control into a result. He maintained that his team deserved at least a share of the points.

“It’s a shame we didn’t take at least one point today because I think we deserved it,” he concluded.

Celtic’s second-half comeback changes everything

Although the opening half ended without a goal, the match became considerably more entertaining after the break.

Celtic initially appeared to be heading towards another frustrating European evening when Jordan Lotomba conceded a penalty in the 51st minute. The opportunity gave the hosts a chance to take control, but Johnstone produced an important save to deny the initial attempt.

However, the danger was not completely cleared, and Beşiktaş managed to turn the rebound into the opening goal.

That moment threatened to leave O’Neill’s side facing another difficult result, particularly after their disappointing start to the Europa League campaign. Celtic had struggled to create enough opportunities before the interval and needed a response.

The manager eventually turned to his substitutes, introducing Osmand and Durán alongside Colby Donovan in the 61st minute. Those changes brought fresh energy and attacking quality into the Celtic team.

Osmand made an immediate impact, scoring just 43 seconds after entering the pitch. The youngster finished following an assist from Callum McGregor, giving the home supporters renewed belief that their team could still rescue the match.

The momentum continued to swing in Celtic’s favour, and Durán subsequently put the hosts ahead with a composed finish in the 78th minute. His contribution appeared to have put O’Neill’s side in a strong position to secure a valuable European victory.

However, Beşiktaş refused to surrender and managed to restore parity five minutes before the end of normal time.

Orkun Kökçü produced a powerful strike to make it 2-2, leaving Celtic with another difficult challenge and threatening to deny them their first three points of the league phase.

Yet the home side responded almost immediately. Durán found the net again three minutes later, completing his brace and restoring Celtic’s advantage.

The late goal sparked celebrations around Celtic Park and ensured that the hosts finally had something positive to show for their European efforts.

O’Neill’s changes provide a crucial victory

The result represented a significant moment for Celtic, who had entered the fixture desperately needing points after failing to win any of their opening three Europa League matches.

O’Neill’s decision to introduce Osmand and Durán proved particularly important, with both attackers directly influencing the outcome. Their performances also strengthened the argument that they deserve greater consideration when the manager selects his starting eleven for upcoming fixtures.

For Beşiktaş, however, the defeat will be difficult to accept. Trossard and his teammates believed their overall performance warranted a better outcome, but their defensive errors and missed opportunities ultimately proved decisive.

Celtic have now secured their first victory of the Europa League campaign, with four league-phase matches remaining. The result provides a much-needed boost, although O’Neill’s players will understand that considerably better performances are required if they are to keep their hopes of progressing alive.

Trossard’s assessment highlights Beşiktaş’s frustration, but Celtic will be more interested in celebrating a victory that could provide the confidence needed for their remaining European fixtures.
