Kevin De Bruyne faces a lengthy spell on the sidelines after suffering a horrific looking knee injury in Manchester City’s League Cup semi-final triumph over Everton.

The Belgium international was stretchered off the pitch with his knee in a brace late in Wednesday night’s clash at Etihad Stadium.

The second-half substitute had scored one and created the tie-clincher for Sergio Aguero as City came from 1-0 down in the second leg to win 3-1 on the night and 4-3 on aggregate.

But De Bruyne’s knee buckled as he fell to the ground at the 88-minute mark and he screamed in agony as he slumped to the turf.

The attacking midfielder had lengthy treatment before leaving the pitch on a stretcher to muted, concerned applause.

De Bruyne will undergo tests at City’s training headquarters on Thursday amid fears he could be out for months.

Speaking to Sky Sports afterwards, manager Manuel Pellegrini said: “It’s difficult to know right now, but the doctor thinks he has some problems with his medial ligament. We will have more news tomorrow but it’s not an easy injury.”
