A good ball playing goal keeper and definitely better number 2 option than Kepa. I watched a few of those Leeds games where he ended up being dropped, and felt really sorry for him as while did make some good saves, was undone by one error each time that resulted in a goal. That spell completely wrecked his confidence but hopefully he will recover in a different environment. He will have come from a team facing a lot of shots to likely facing a fraction of that but needing to be ready to make those crucial saves, which means he needs to be mentally prepared.
While Raya is undisputed no1, I think it is important to get Meslier ready for when we might actually need him. Would even be tempted to start him against Coventry just to get some game time time early in the season. We can then bring back Raya and Meslier can have the cup games.
