Richarlison and DCL (who is now injured again btw but it probably is to be safe than sorry but wouldn't be surprised if he's reaggravated the injury badly) are Premier League players.Neither will Richarlison have by the time he comes back, but I assume he’ll come straight back in. DCL hadn’t played for 3 months and got through 90 minutes. Mykolenko should go straight in.
Mykolenko hasn't been. He'll need time.
