My perspective was it had more to do with Alwyn second guessing himself, early on he would throw himself at everything and really crash into players. After the two big injuries, I think he didn't go as hard at the end (he would chase hard and put pressure on but the manic desperation turned into self preservation a bit and fair enough too).
He used to get my out of my seat at the game or off he couch at home and it is the same with Tippa now. Hopefully he has better luck with injuries and keeps mixing his skills with hardness at the contest.
Also this game and the start of the season should settle the back forward debate. He is perfect as a HFF causing havoc from the center square to the goal square.
Defenders beware, particularly in the wide open spaces of the G.
