Arsenal hero Lee Dixon says the players need to start challenging manager Unai Emery's methods.

The Gunners have been struggling under the Spaniard this season and sit a staggering 17 points behind Premier League leaders Liverpool after just 12 games played.

Dixon said on The Season So Far: "From [having] a shot at one end to conceding a penalty at the other end in the space of 20 seconds - that cannot happen, that has to stop.

"Now that game was Watford - I could have done [Aston] Villa at home, I could have done Liverpool away when he played a narrow midfield and let the Liverpool full-backs run the game.

"I could have picked any number of games and done the same analysis and just overlaid it onto the pitch.

"It's happening every week - that has to stop and the players have got to go 'We don't know what you're doing gaffer, can we change it? Can we change something?'.

"But there's no leaders in that team, there's no Patrick Vieira to go 'boss can we change the system or something?'. Unai is banging the drum about how he wants to play and the players can't do it."
