Martin Keown believes Alexis Sanchez won't score as many goals as Diego Costa this season - and also feels he can improve his game by learning from Lionel Messi.
Costa has made a sensational start to life in the Premier League, scoring seven goals in his opening four games.
And Keown feels Sanchez, who has scored two, won't be as clinical - understandable as he is not primarily a centre-forward - though he does feel he can improve in the final third by learning from his former team-mate at Barcelona, Messi.
He replied: "Sanchez will chip in with his fair share but not in the same way as Costa. At the moment it’s more about the relationship between Sanchez and the players around him. He gets smothered by defences sometimes.
"Sanchez takes a lot of touches of the ball and the team copy his enthusiasm. But I think I’d like him to slow it down just a little.
"Lionel Messi’s first touch is often just a quick one to another player to draw defenders in – maybe that’s something Sanchez could work on."
As Opta stats show, Sanchez has scored twice for Arsenal so far this Premier League season, also winning 10 dribbles.
Keown's comments about the amount of touches the Chilean takes, meanwhile, are interesting because only Aaron Ramsey and Mathieu Debuchy have taken more than Sanchez, who moved to the Emirates Stadium from Barcelona for £35 million this summer.
The Gunners travel to Aston Villa on Saturday for their next league clash, on the back of a 2-0 humbling at Borussia Dortmund in the Champions League.
