Rio Ferdinand and Martin Keown involved in heated argument over Arsenal this season and it's instantly gone viral

Rio Ferdinand and Martin Keown were involved in a heated argument following Arsenal's bruising Champions League defeat to Inter Milan.

Arsenal suffered a 1-0 defeat at the San Siro as Hakan Calhanoglu scored the only goal of the game in Wednesday's tie.

Calhanoglu converted a penalty in first-half injury time as Mikel Arteta fumed at the decision to award the spot-kick.

After the game, Ferdinand, Keown and Italian football expert James Horncastle delved into the match, with the Manchester United legend and ex-Arsenal man clashing on TNT Sports.

Ferdinand began by highlighting Inter's absentees, with Keown disagreeing with his counterpart's claim.

Horncastle weighed in: "I think Simone Inzaghi would love to have Mikel Arteta's budget."

The journalist then listed the players Inter have been forced to sell, including Andre Onana who joined Man United.

Keown fired back by defending his old side's showing in Italy and rejected the notion the club are going through a crisis amid back-to-back defeats.

"I don't think there's a massive crisis for Arsenal... I don't think they are that far away from getting it right," he said, before highlighting Ethan Nwaneri's impressive cameo.

He concluded by praising Inter as he backed Arsenal to turn things around.

Ferdinand then turned to Laura Woods and said: "Why are Arsenal people so touchy!? No one's having a dig... we're not having a dig."

Speaking after the game, Arteta said: "With the manner of situation, chances that we generated, we should have scored a couple of goals at least and that’s on us.

"The way the team played, that was us tonight. Level of energy, level of quality, how we arrive in the box, how we dominated a team that’s one of the best in Europe. In their stadium, very proud.

"It was decided in the boxes which is the Champions League and every decision in the box makes a difference, it’s clear."

The Gunners resume their league campaign on Sunday when they face London rivals Chelsea at Stamford Bridge.
