Marseille head coach Igor Tudor believes that Nuno Tavares is capable of playing for Barcelona or Real Madrid after working with the Arsenal loanee this season.
Tavares, 23, joined the French giants on a season-long deal last summer after falling out of favour at the Emirates just 12 months after moving to London from Benfica in an £7million deal.
The Portuguese international endured a difficult maiden campaign in the Premier League but has made a major impression on the other side of the channel, netting six goals in 24 Ligue 1 appearances. And his current boss, Tudor, is adamant that Tavares is good enough to play for one of Europe's elite clubs in the future if he keeps improving.
