Chelsea ace Willian believes Philippe Coutinho's move to Barcelona has improved his game.
The former Liverpool attacker hit a stunning goal in Brazil's World Cup win over Costa Rica.
Willian said, “He is an unbelievable player. A fantastic player. I am happy because he plays for Brazil! I was happy for him because he scored his first goals for us.
“When he played at Liverpool he was this player. But I think in football we have to improve and I think he is doing that. He has improved a lot. He has done very well and I am really happy for him."
