Chelsea centre-back David Luiz has revealed his excitement at the club's transfer deadline capture of midfielder Raul Meireles from Liverpool.
The ex-Benfica star is convinced that manager Andre Villas-Boas has made an inspirational signing and believes the arrival of the Portugal international could be the catalyst for success.
Luiz feels the Portuguese-speaking players have developed a greater understanding with Villas-Boas at the helm and is certain it will have a positive effect on dressing room morale.
"Villas-Boas deserves to be in charge at Chelsea and I am convinced he will succeed in England," said the Brazil international in the Daily Mirror.
"Every coach has a different style of work. Andre is different to Ancelotti and I am hoping for more success than last season.
"I had respect for Ancelotti but, of course, it is easy when the manager also speaks my language.
"During training sometimes he speaks Portuguese to the Portuguese speakers and it's easier to understand. Maybe we could use it as a secret tactic in matches.
"Every day we are getting better and I bet we will have success this season. We have made good signings and I think Raul Meireles can be a big player for us.
"We played against each other in Portugal and he was difficult to stop. It is sensational he can increase our level on the pitch."
