Chelsea winger Willian believes new Liverpool signing Roberto Firmino has what it takes to thrive at Anfield and will be helped by the presence of his compatriot Philippe Coutinho in his attempt to settle quickly into the Premier League.

Liverpool announced the signing of the Brazil international from Hoffenheim on Wednesday 24 June after they paid £29m ($45m) to the Bundesliga side to secure his services, according to the BBC.

The versatile Brazilian forward has become manager Brendan Rodgers's fifth signing of the summer after completing the additions of midfielder James Milner, striker Danny Ings, goalkeeper Adam Bogdan and promising defender Joe Gomez.

And Willian, who is playing in the Copa America alongside Firmino, has now backed his compatriot to make an impact at the Premier League alongside Coutinho.

"He has skills to play for Liverpool. He's a great player. He knows how to score and is strong," the Chelsea winger said to reporters, as quoted by AS.

Willian made a similar move to the Premier League in the summer of 2013 when he switched from Anzhi Makhachkala to Stamford Bridge after the Blues paid around £30m to secure his services.

And even though some South American stars have struggled to make the impact expected in the Premier League, the Brazilian has since become a crucial player for manager Jose Mourinho.

The Chelsea winger admits the adaptation from Brazilian to English football is not easy but believes Firmino has the skills to do it, having already played in a top European league.

He said: "Obviously, British football is played differently, very quick and aggressive and it is tough to adapt but I believes he can manage to do it. And other players like Philippe Coutinho, who will also play with him, can help him to make the transition."
