Roy Keane produces hilarious reaction after Theo Walcott claimed Arsenal are a bigger club than Man United

Roy Keane produced a brilliant reaction when Theo Walcott claimed Arsenal are a bigger club than Manchester United.

Last season, Arsenal shocked the world of football after they mounted an unexpected charge for the Premier League title.

However, despite leading for the majority of the season, the Gunners were eventually overhauled by Pep Guardiola’s rampant Manchester City side.

Ahead of Sunday’s mouth-watering clash between Arsenal and United, Walcott, who is part of Sky Sport's punditry lineup, was asked to choose which club is bigger.

The former Arsenal man said: “Arsenal finished above United, so if you're going right now, for me, I'd have to say them. I feel like they're a bit more organised. Especially behind the scenes as well.”

United legend Keane failed to keep a straight face as he smiled whilst Walcott was making his point.

After tapping Walcott on the back, Keane said: “So naive and young, huh? So naive and young.

“Of course it's United. Of course it's United. Don't be silly.”

This summer, Arsenal have further strengthened after signing the likes of Kai Havertz, Jurrien Timber, Declan Rice and David Raya.

Keane was then asked whether he is convinced by Arsenal’s title credentials, he said: “No. Not really.

“Obviously they've strengthened the squad, they were brilliant last season, particularly at the start of the season.”

Keane continued: “But we were here towards the end of the last season where they ran out of steam physically and mentally and I still think they're short.”

The former United captain then questioned Mikel Arteta’s formations. He said: “I didn't know there were that many formations you could play in football but there you go.

“Sometimes you need to simplify football because they have a lot of good players, they had a lot of good momentum last year but they did come up short.”
