Vincent Kompany has been taken to a hospital in Munich by ambulance from Bayern Munich's training ground.

Kompany, 40, has been suffering from a viral infection which is said to have caused problems with old scar tissue, leaving him with difficulties climbing stairs.

BILD report that a helicopter had landed at Bayern's training ground earlier on Friday. The former captain of Manchester City, who won four Premier League titles, later went to hospital in an ambulance.

Sky Sports Germany say Kompany collapsed after Friday's training session ahead of their Bundesliga match away at Freiburg this Sunday.

After a 2-2 draw with Arsenal in the Champions League on Wednesday, Kompany had said: 'As a coach, you always want to do everything and accomplish everything. I caught a pretty nasty virus last week, and of course I didn't listen to my body, and then at some point my body said: "Stop now!"'
