This summer Chelsea needed to move in the market for a new left-back, with Ashley Cole and Ryan Bertrand's respective departures leaving them with just Cesar Azpilicueta to play in the position.
With that in mind Jose Mourinho continued his raid on Atletico Madrid. The Brazilian international cost Chelsea £15.8 million this summer. Filipe Luis joined returning loanee Thibaut Courtois and £32 million striker Diego Costa in swapping the Vicente Calderon for Stamford Bridge in the summer.
And Luis has now been talking about the two coaches of these clubs. Before working under Mourinho he was under the guise of the enigmatic Diego Simeone.
And he says the two are different, although they also have some things in common:
"They're completely different coaches, but they have one thing in common: their ambition to win with their clubs. They put their teams together with a lot of ambition. I'm in it for the long haul. Everyone here wants to play and when you don't play, you can't be altogether happy, but I came to
Chelsea to win trophies. The team always comes first, over and beyond any one player."
Simeone has developed a reputation as one of the best managers in the world in recent times, leading Atletico to a La Liga title and Champions League final in 2013-14.
But Simeone has another difference, he played Luis. The Brazilian has so far struggled for regular first team football at the club but he clearly has the will to tie down the left-back spot at the club.
In the same interview, as reported in Marca, Luis also revealed that he has not been asked to act more defensive at the club by Mourinho.
"It's a very long season and we don't have a big squad. Everyone will get their chance and I'll try to grab mine with both hands. That's what they signed me for [attack from left-back]: to do what I did at Atlético. All I've been told is to do my best for the team and to try to help us not concede goals."
