Watford winger Ismaila Sarr has returned to training with Senegal and could be in line to play a part in their African Cup of Nations quarter final against Equatorial Guinea in three days' time.

Sources close to the player have said that there is at least a possibility he makes an appearance in Sunday's last eight clash, although the expectation is that it would almost certainly be as a substitute rather than in the starting XI.

A post on the Federation Senegalaise de Football's Instagram page showed Sarr training with his side at their camp in Cameroon, accompanied by the caption: "Ismaila Sarr did all of the day's training with the group".

It could be that Senegal coach Aliou Cisse chooses to be a bit more patient with the winger, with his side heavy favourites to get past Equatorial Guinea this weekend, but either way it appears increasingly likely he will make his first appearance since injuring his knee in the 4-1 win over Manchester United in November during the tournament.

Should Senegal get through their quarter final, as they are expected to, they would face the winner of Tunisia versus Burkina Faso on February 2, which would give Sarr almost a week's worth of work on the training pitch before a potential return, if Cisse opts to wait a little longer.

The player's knee injury had originally caused a dispute between the Hornets and the Senegalese Football Federation before it was mutually decided that the player would travel to Barcelona to undergo rehabilitation under the watch of knee specialist Dr Ramon Cugat. He returned to Cameroon earlier this week

Should Senegal be knocked out of the tournament on Sunday, Sarr theoretically could be in line to play some part in Watford's next game, away at Burnley on February 5, depending on his fitness.
