London - Manchester City manager Pep Guardiola has confirmed that Vincent Kompany will be out for 'weeks' because of a fresh injury to his knee.
The 30-year-old Kompany, who has been plagued by injuries in recent seasons, was taken off after being concussed during City's Premier League victory over Crystal Palace on Saturday and was not included in the squad for their Champions League game against Borussia Monchengladbach on Wednesday.
However, Guardiola has revealed that the Belgian, who has only just returned following a four-month lay-off after undergoing groin and thigh surgery, suffered ligament damage to his knee.
Guardiola told reporters on Tuesday: "He has a problem with his knee. He could be out for weeks. He's sad and I'm sad. It's a long time he doesn't play.
"He is in the best hands so he can recover as soon as possible. He will make the best treatment possible. The doctor told me a few weeks (that Kompany will be out). We'll see. It is ligaments."
Kompany has only played two league games under Guardiola this season following on from last season when the club captain only made 22 appearances, his fewest since he joined City from Hamburg in 2008.
The Sky Blues next Premiership clash is at Turf Moor Stadium where they will encounter a Burnley side looking to grab a point from the game after suffering a 4-0 defeat to West Bromwich Albion over the weekend.
