Arsenal manager Arsene Wenger has coached many footballers over his 20-year career at the North London club.

It is no surprise that he is not best friends with all of them, but there is one who recently made a dig at the Frenchman.

Paul Merson came through the Arsenal ranks in 1985, but spent just one year under Wenger's guidance between 1996 and 1997 before moving on to Middlesbrough.

The now-Sky Sports pundit has not held back in his criticism of the manager before, and in 2014 the pair had a public war of words.

It seems that Merson may have reignited the feud by suggesting that Harry Redknapp is a better manager than Wenger, who has won three Premier League titles and seven FA Cups during his time at Arsenal.

While on Sky One's A League of Their Own, Merson said:

"People say he's [Redknapp] a wheeler-dealer and it's so disrespectful. Tactically, he's one of the best I've worked with. If Arsene Wenger had Harry Redknapp's tactical nous, Arsenal would win the league."

During Thursday morning's press conference, Wenger was asked by reporters about Merson making a return to the professional game at 49 to play for Welsh club Caerau.

The Frenchman's response...

"We speak about professional football here."
