Beşiktaş manager Vincenzo Italiano has claimed his side threw away three points against Celtic after Martin O’Neill’s men completed a dramatic 3-2 Europa League comeback at Celtic Park.

However, Celtic’s substitutes transformed the game.

Callum Osmand equalised with his first touch before setting up Camilo Durán to put the Hoops ahead.

Beşiktaş captain Orkun Kökçü made it 2-2 in the 86th minute, but Durán responded almost immediately to secure Celtic’s first three points of the Europa League league phase.

Italiano was left furious with his team’s defending, suggesting the visitors had effectively handed Celtic the victory.

In post-match comments published on Beşiktaş’s official website, the manager said:

“I’m extremely disappointed tonight. We need to find a solution for our defense. We have been conceding too many chances and making too mistakes lately. We’ve thrown away three points that were within our reach. We need to be as tough and focused as we used to be.”

The Beşiktaş boss also criticised his players during his post-match press conference.

According to Turkish news agency DHA, Italiano claimed his side had gifted Celtic all three goals and described the defensive errors as avoidable.

He was particularly unhappy with how Beşiktaş conceded the winner just moments after Kökçü had brought them level.

Italiano felt his players should have stopped the attack before Durán was able to get into a scoring position.

While Italiano focused on Beşiktaş’s mistakes, Celtic’s second-half improvement was difficult to ignore.

O’Neill introduced Osmand, Durán and Colby Donovan in the 61st minute, with his side trailing 1-0.

Osmand needed less than a minute to make an impact, finding the bottom corner after collecting Callum McGregor’s pass.

The 20-year-old then turned provider, sending Durán through to round Alexander Nübel and finish.

The Colombian’s second goal came after Kieran Tierney’s ball reached him inside the penalty area, with Durán showing quick feet before stabbing his effort home.

It was a remarkable turnaround for Celtic, who had failed to register a shot on target during a disappointing first half.

The defeat was Beşiktaş’s first of the Europa League league phase after an unbeaten opening three matches.

Italiano’s frustration was understandable given how close his side came to leaving Glasgow with at least a point.

However, Celtic’s attacking changes forced Beşiktaş to defend situations they had largely avoided during the opening hour.

Osmand’s movement created space, while Durán’s direct running repeatedly troubled the visitors’ backline.

The win leaves Celtic with three points from four Europa League matches, keeping their hopes of progressing beyond the league phase alive.
