Arsenal needs the injury suffered to Myles Lewis-Skelly not to be too bad.
Arsenal managed a 3-0 win over Dinamo Zagreb in the Champions League as Mikel Arteta's side took a big step towards qualifying for the next round.
But they did it without Myles Lewis-Skelly, who has been a feature of the backline for the last month with the Hale End star feeling something towards the end of the 2-2 draw at home to Aston Villa.
As such, Lewis-Skelly wasn't involved in Arsenal's win over Zagreb that saw Declan Rice, Kai Havertz and Martin Odegaard, all find themselves on the score sheet.
Given the sheer number of games that the Gunners have played over the last few weeks, that can take a toll on even the most seasoned veterans, let alone an 18-year-old like Myles. Given the state of the injury list, the Gunners can ill-afford another player to go down, particularly one like Myles who has come on in leaps and bounds this season.

So, Myles might have been rested as a precaution, and given how quickly the games are coming, it made sense to give him the night off and let Oleksandr Zinchenko get a rare start.
But while Lewis-Skelly didn't feature, Ethan Nwaneri did.
Another Hale End product who has been sidelined for the last couple of weeks, Nwaneri made his return against Zagreb and immediately picked up where he left off, making life tough for the Dinamo defenders.
The Gunners took a big step towards qualifying for the next round and with Wolves up next in the Premier League, it remains to be seen if Lewis-Skelly will take part.
But at least Nwaneri is back amongst the action as the injury troubles appear to be slowly working themselves out.
