Alexis Sanchez faces long spell on sidelines: Details here

"Alexis Sanchez underwent medical tests earlier this morning at the Humanitas Institute in Rozzano. Results revealed a joint dislocation in his left ankle which has caused damage to the peroneus longus tendon," a statement read.

"The player will meet for further consultations with Professor Ramon Cugat in Barcelona on Wednesday, where they will seek to reach a decision on whether surgical intervention is necessary."

Meanwhile, Chile coach Reinaldo Rueda said the forward could be out for up to three months.

"We have to see what diagnosis they make in the club, because it is decisive for us," the Chilean coach said.

"If there is surgery we could lose him two to three months, if not, it could be a matter of weeks. That depends on the club."

Sanchez joined Inter in the summer for a season-long loan.

He has featured just four times this season so far.

The Chilean made two late substitute appearances in the 1-0 wins over Udinese and Lazio.

He has also scored just once and things haven't gone as planned.

This injury is now a fresh cause of concern for Sanchez, whose career looks out of sorts.

Sanchez arrived at United with a lot of expectations.

He was superb in his spell at Barcelona and Arsenal.

One expected him to carry on with the form he endured at the Emirates.

However, Sanchez fell from grace and netted just five goals during his time at United.

He hardly got going and was injured frequently. That didn't help United's cause.

Sanchez has been out of form and injuries have seemed to take a toll on him.

He looks past his prime and time is running out for the Chilean.

All this leaves United in a fix. They will find it difficult to sell him.

The player's confidence has taken a hit.

And at the moment there is no respite.
