Arsenal legend gives Chelsea tip: Here's how to breach PSG defence…

A centre back great has identified a weak-point in the Paris Saint Germain rearguard and believes the Blues can exploit this in the Champions League.

He may be touted as one of the best centre backs in world football, but even Thiago Silva has his flaws, writes former defensive legend at Arsenal Martin Keown in his Daily Mail column ahead of Paris Saint Germain's trip to Chelsea for the second leg of their Champions League quarterfinal tussle.

Keown, now 47, enjoyed his best years at Highbury and Ashburton Grove, claiming three Premier League titles, a hat-trick of FA Cup winners medals and a UEFA Cup Winners Cup. He was also a key component of the Invincible team - who went an entire season unbeaten in the division.

"Thiago Silva is a class defender, but he showed last week he can occasionally dive in," commented Keown.

PSG defeat Chelsea 3-1 at the Parc des Princes and while Ezequiel Lavezzi stole the headlines due to his emphatic strike after just four minutes. Not all of PSG excelled, though, as Silva mis-timed a challenge on Oscar which allowed Eden Hazard to convert a useful penalty goal - an away goal that has given Chelsea something to play for at Stamford Bridge this evening.

Keown believes Chelsea's quality attackers such as Hazard should target Silva and run at him in order to panic him into giving away a foul.

"Chelsea’s attacking midfielders buzz around the pitch so quickly, so if they can run at the defence they can win free-kicks in dangerous areas or even a penalty," Keown concluded.
