Neymar: Brazil forward to miss the first leg of Paris St-Germain's last 16 Champions League tie with Barcelona

Neymar has scored 13 goals in 17 games this season for Paris St-Germain

Neymar will miss the first leg of Paris St-Germain's last-16 Champions League tie against his former club Barcelona with a thigh injury.

The Brazil forward was injured in PSG's French Cup victory over Caen on Wednesday.

Mauricio Pochettino's side travel to the Nou Camp on Tuesday (20:00 GMT).

PSG say they expect Neymar, 29, to recover in around four weeks, which could see him return for the second leg on 10 March.

• Every year, since 2014, Neymar has been either unfit or suspended around this time of year

Writing on his Instagram page on Thursday Neymar said: "The sadness is great, the pain is immense and the crying is constant.

"Once again, for a while, I will stop doing what I love most in life, which is playing football.

"Sometimes I feel uncomfortable because of my style of play, because I dribble and constantly get fouled, I don't know if the problem is me or what I do on the pitch."

Neymar helped PSG reach their first ever Champions League final in August and has scored 13 goals in 17 appearances this term.

It is a second blow for Pochettino, with winger Angel di Maria already ruled out of the match with a thigh injury.
