Everton star Yannick Bolasie could be set for a long spell on the sidelines after damaging the anterior cruciate ligament in his right knee.
The winger sustained the problem during Sunday’s 1-1 home draw with Manchester United and is expected to go under the knife before the end of the week.
Bolasie was signed from Crystal Palace in August for a fee believed to be in the region of £25m and has so far played in every game following his arrival.
The 27-year-old, who has struck up a decent partnership with Romelu Lukaku, now faces a long spell out of the side.
Everton are yet to give an indication of how long he will be sidelined but Bolasie could now struggle to play again this season.
A statement on the club’s website read: “Yannick Bolasie will undergo surgery after sustaining a serious knee ligament injury against Manchester United on Sunday.
“Bolasie picked up the injury in the second half of the 1-1 draw at Goodison and was replaced by Enner Valencia.
“Scans have now confirmed anterior cruciate ligament damage to the right knee.
Bolasie will undergo surgery in the next few days.” The setback comes as a further blow to boss Ronald Koeman, whose side have won just one of their last nine Premier League outings.
Saturday sees the Toffees travel to Watford, a game they are 2.40 to win, with the draw 3.25 while the Hornets are 3.10.
