David Moyes admits that Arthur Masuaku is not really suited as a left-back, but insists the club are happy with his performances.
Masuaku has primarily come off the bench this season, although he started against Manchester City, in the game in which Aaron Cresswell sustained his back injury, while he also scored the winner against Chelsea and started versus Burnley. 
Moyes admits that Masuaku is not absolutely suited to life as a left-back and has bemoaned the fact that there are a number of injuries in his backline.
Speaking to reporters ahead of the game against Arsenal, he said: “We are happy with Arthur but he is probably better as a wing-back than a left-back but he is more than capable. We need Cressy to be fit and Ben Johnson and Ryan Fredericks to get fit.
“If we get one of them fit then maybe one of them could play more as an orthodox left-back. It is in my mind that we could possibly look to try and play a back three but we could do with one of our centre-halves being fit for that and we need to try and get that sorted but at the moment we have not got Kurt or Angelo back so we are a little short in those areas.”
Moyes accepts that having Cresswell back in the squad will help with tactical flexibility, as he can play in a back three or a back four.
He added: “Yes definitely. Aaron coming back helps us comfortably play a back four or three so that is why Cressy has been so good for us over the last year or two.
He gives us the flexibility to chop and change, we can start one way then go another if we need to so Cressy has been really important to us and how we play.”
As well as Cresswell’s delivery of Corners and Free Kicks is a major attacking threat.
I’ve said already this week that if Cresswell is unfit then using Longelo at Left-back with Masuaku playing further forward (at the expense of Benrahma) could be a useful option! 🤔
