Filipe Luis left Atletico at the end of that campaign to join Chelsea but, after failing to keep a regular first team place, he has returned to Spain to find Simeone’s side once again ready to upset clubs with bigger budgets.
“I have found myself with team mates with more hunger and more ambition,” Filipe Luis told a news conference in Madrid.

“Players like (Diego) Godin, Tiago (Mendes) and Koke they have made history here. They know how difficult it is but it is also a challenge to keep going and try to win more."

Filipe Luis said there was no chance Atletico would hold back despite a tough La Liga match with Valencia at the weekend.
