Arsenal legend Emmanuel Petit has heaped praise on the centre-back partnership of Gabriel Magalhães and William Saliba.

Mkel Arteta's table-toppers have improved in every department after coming fifth last season - with a handful of key partnerships.

And ex-midfielder Petit reckons nowhere is that more clear in defence.

The Frenchman told Les Transferts: "They form a homogeneous and effective defensive duo. They also leave few opportunities for the opponent.

"Even when trailing, they never give up and show great strength of character and willpower."

"They are in perfect harmony."
