From the moment the Premier League fixture list was announced, Unai Emery must have known he was in for a tough start.

The sight of the former PSG and Sevilla coach in the dugout was always going to be a strange one after 22 years of Arsene Wenger.

So far, it hasn't been a welcome one either. Two games in and the Gunners are yet to secure a point in the league following defeats to Manchester City and Chelsea.

The majority of fans admit it is too early to judge their new manager given the calibre of opposition his side have faced.

All that can be gleaned so far are drips and drabs of Emery's tactics: how he wants Arsenal to play, who he favours in the squad, and most importantly, if there is any sign of improvement after missing out on the top four last season.

However, pundit Paul Merson - yes, we know - has been watching his former side very closely and he has identified a problem with the new system.

Namely, he believes Emery does not have the right players if he wants Arsenal to press like some of their top six rivals.

Emery has the wrong players

"He hasn't got the players to have a 20-yard gap between defence and attack, working hard. Ozil and Mkhitaryan are not those type of players," Merson writes for Sky Sports.

"If you were building a team tomorrow, you'd want to play a high pressing game, work as a team, not to have gaps between the lines, and you're not buying [Mesut] Ozil and [Henrikh] Mkhitaryan.

"If you go the Arsene Wenger way, wanting to play entertaining, free-flowing, great football, then Ozil and Mkhitaryan will walk in any team in the world. But they will not get in teams that want to press!

"I don't know if the current crop have gone past being able to learn that way of playing. That's my concern. I don't mean regarding their age, but in the way they play the game.

"Ozil's future? I don't know. I'm a big fan of him, he's a quality player, but sometimes you watch him and the game passes him by."

Merson gets his fair share of stick but on this occasion, he makes a valid point.

It may just take a minor miracle to get Ozil and Mkhitaryan running.

There has already been plenty of debate about whether Arsenal players are getting to grips with Emery's tactics.

Jamie Carragher and Gary Neville had a heated discussion about that very topic on Monday Night Football, with the ex-Liverpool defender imploring the Spaniard to adapt to the Premier League.

If Emery's system does not start to work soon, he could have big problems.

Arsenal's next test comes this weekend against West Ham United.
