Barcelona have announced Philippe Coutinho suffered a hamstring injury during defeat to Real Madrid on Saturday.

The Catalans were beaten 3-1 by their arch rivals over the weekend but their misery has been compounded by the loss of one of their key attacking stars.

In a statement on the club's official website, Barcelona did not confirm how long Coutinho will be out for as 'it depends on how the injury evolves'.

AS reports the Brazilian attacker is expected to be out for three weeks - which will rule him out for crucial LaLiga and Champions League matches.

Barcelona's next game sees them travel to last season's Serie A champions Juventus in Europe's premier club competition, while Coutinho could also miss the league trip to Alaves next weekend as well as home games with Dynamo Kiev and Real Betis.
