Analysis: A near perfect day but injuries a worry for Arteta

It was nearly a perfect afternoon for Arsenal with a new signing unveiled, Viktor Gyokeres getting off the mark and a debut given to the highly rated Max Dowman.

Injuries derailed Arsenal's title bid last season and with Kai Havertz unavailable with a knee injury and now question marks over the fitness of Martin Odegaard and Bukayo Saka, Mikel Arteta will be hoping he won't have to contend with the same issues this season.

Arsenal came into this transfer window with the aim of increasing the depth and quality of the squad and Arteta will now have to use the £250m of resources that he has brought in during this summer window to bring silverware to the club.

When Eberchi Eze entered the pitch wearing his new number 10 shirt the noise inside the stadium was nearly as loud as the celebrations that followed each of the five goals that the Gunners scored. Eze's quality is going to bring a different dynamic to the Arsenal attack.

Dowman has been one of Arsenal's brightest sparks throughout pre-season and had already won two penalties against Newcastle and Athletic Bilbao.

He again showed why there is so much excitement about his potential when he came on against Leeds and the winger's ability to beat his defender was shown again when he won a penalty for Arsenal's fifth goal.

Arsenal are cautious about putting too much pressure on the 15-year-old but when he continues to impress at senior level, they will find it hard to stop the hype around him.
