Manchester United striker Zlatan Ibrahimovic could face retrospective punishment after he grabbed Fenerbahce defender Simon Kjaer around the neck during the Reds' 2-1 defeat in the Europa League. The out-of-form Swede was involved in an angry confrontation with the Dane near the touchline - but referee Milorad Mazic did not take any action at the time.

Ibrahimovic, 35, was introduced as a first-half substitute for Paul Pogba against the Turkish side, after United's world-record signing limped off with a dead leg. While Ibrahimovic failed to find the net, he did make an impression on Kjaer, grabbing the defender by the throat and shouting in his ear.

The confrontation was quickly broken up by Uefa's fourth official and United boss Jose Mourinho, who pacified both players during the incident. Ibrahimovic, though, was clearly incensed by the perceived provocation from Kjaer, as he continued his arguments after a foul had been awarded.

Mazic appeared to miss the clash, but Uefa could still review footage of the incident. The United striker may be handed a one-match ban if the European football governing body consider his behaviour to be worthy of a red card.

United face Dutch side Feyenoord at Old Trafford in their next Europa League fixture. The Red Devils trail Feyenoord and Fenerbahce by one point in Group A following their humbling defeat to the Turks on Thursday (3 October).

A ban would cap another miserable night in a United shirt for Ibrahimovic, whose form has fallen away markedly in recent weeks. The record-breaking Swede again failed to find the net during the game in Turkey and his place in the team has come under scrutiny in recent weeks.

Ibrahimovic missed a host of chances against Burnley in United's last Premier League game and former Arsenal striker Ian Wright recently questioned Mourinho's decision to sign the former Swedish international. "When you look at him, his all-round play has just not been good enough. His movement has not been great, I'm going to be totally honest, I'm not sure too many other teams would have signed him, even on a free," Wright told The Sun.

"You look at the way Man City are playing, the way Chelsea are playing, Liverpool, Arsenal, Spurs, all vibrant, teams with pace and exuberance. And you look at Man United, it's slow, and he's got a massive part to play in that. I've not seen Ibra play well for 10-15 games, and Man United need it especially the way they are playing."
