Mikel Arteta has a lot to consider when he sits down to reflect on Arsenal's pre-season tour of the United States.

Three games played, two wins, ten goals scored, all three summer signings getting minutes under their belts and after losing to Manchester United last weekend, the Spaniard will have been delighted with the response against Barcelona as the Gunners ran out 5-3 winners ahead of their return to London.

With an Emirates Cup clash against Monaco and a Community Shield showdown with Manchester City pencilled in before Arsenal get their Premier League campaign underway at home to Nottingham Forest two weeks on Saturday, Arteta should have a good idea as to what his starting line-up will be.

Based on decisions over the course of last season and barring any injuries, it's safe to assume Aaron Ramsdale, Benjamin White, William Saliba, Gabriel Magalhaes, Martin Odegaard, Bukayo Saka and Gabriel Jesus will all start the opener thus leaving four spots up for grabs in defence, midfield and attack.

Oleksandr Zinchenko hasn't featured at all in pre-season so it's touch and go as to whether he will be available for selection but in Kieran Tierney, Jurrien Timber, Jakub Kiwior and Takehiro Tomiyasu, Arteta is not exactly short of options at left-back if the Ukraine international isn't ready to return.

The same can be said in the defensive midfield position with Thomas Partey and Jorginho on standby if record signing Declan Rice is still struggling with a tight calf that kept him out of the Barcelona game. Although, it's in the attacking midfield position where a dilemma has emerged thanks to Leandro Trossard.

While the Belgium international scored twice against the La Liga champions when deployed as a left-winger, it's worth remembering that he operated as the left-sided midfielder - the role earmarked for £65million summer signing Kai Havertz - against the MLS All-Stars and Nurnberg.

Clearly, a player highly valued by Arteta because of his versatility, Trossard is certainly doing all he can to ensure he's in the starting line-up on August 12 and if his pre-season performances have been a clear message to the Arsenal manager, then it's been heard loud and clear.

"It's great to see him scoring. He's been working so hard and came in a really good condition for pre-season," the Spaniard said after the Barcelona win. "He gives us something very different to the other wingers we have and he has got incredible versatility and unpredictability to play in different positions too. It will be good for his confidence, for sure."

Now, here's where things get a little tricky. For Trossard to start against Forest, you have to imagine it will be at the expense of either Havertz or Gabriel Martinelli. And when considering the price-tag for one and the goalscoring record for the other, ultimately Arteta has a big decision to make.

But Trossard is proving impossible to ignore. He's shown since arriving for £21million from Brighton in January that he can pick the right pass in the final third and on current form - as Arsenal's top scorer in pre-season - should start against Forest but the options at Arteta's disposal means it far from certain.
