Former Atlético Madrid boss Quique Sánchez Flores has hailed Chelsea following their win over the Spanish side, but warned them not to think they’ve won the tie yet.

The Blues took on Diego Simeone’s side earlier this week in the first leg of their Champions League last 16 clash.

It proved to be a tight affair between the two sides, with Chelsea coming out on top courtesy of Olivier Giroud’s superb overhead kick.

The 1-0 victory means the tie is perfectly balanced for the second leg at Stamford Bridge, with Chelsea out in front and favourites to progress, particularly with an away goal to their name.

They, though, have a history of famous comebacks, and tougher ones at that, with their famous win over Liverpool ten years under his leadership a famous example.

And it is because of that Sánchez Flores has warned them not to think the tie is over, even though he admits his old side will find it tough against a team he is impressed by.

“Football has changed a lot,” he told MARCA.

“The systems are very contextualised. Suddenly there are teams that start with a back four and end up with a back five? But very big teams like the Belgian national team do it.

“In the end, they end up with a defence of six, and this is because the full-backs go so long that they end up drowning the centre-backs.

“From what I have experienced in the Premiership, Chelsea is one of the teams that plays the fastest and has a brutal danger.

“If they (Atlético) already beat Liverpool and came back, which was a miracle ten years ago, why can’t they do it this year?

“Surely Cholo will have read the game and drawn conclusions.”
