In a crushing blow to Manchester United, star striker Zlatan Ibrahimovic has been ruled out of the season.

He suffered a gruesome knee injury in the Europa League victory against Anderlecht.

The Swedish striker landed awkwardly on his right leg after attempting to win a header right at the end of normal time on Thursday night as United searched for a winner to send them through to the semi-finals.

The 35-year-old hobbled off the pitch and down the Old Trafford tunnel to be replaced by Anthony Martial at the beginning of extra-time.

The striker has been instrumental for United. He has scored 28 goals for the club and produced nine assists in 41 matches.

Defender Marcos Rojo also suffered a knee injury and was stretchered off in the first half.

“We are in trouble,” said manager Jose Mourinho. “In this moment, Eric Bailly played six matches in a row, and we lost Marcos Rojo. We don’t have Jones or Smalling. “We are in trouble and now we lose Zlatan too, but in attack, we have options and Rooney is coming, and let’s see if  (Juan) Mata can also return before the end of the season. Let’s see what happens.”

United are currently fifth in the Premier League, four points off fourth-placed Manchester City, with a match in hand.

Furthermore, they were drawn against Celta Vigo in the semi-finals of the Europa League on Friday afternoon.
