He was causing problems for defences way better than what he'll find in this league as recently as last season, so -based purely on his ability- this is a good move.
But aside from the concern that we are already well stocked for his best position, I'd wonder why Wham are prepared to jettison him on a loan deal so soon after signing him. I get that Arnautovic, Ayew, or whoever are probably ahead of him in the pecking order. But with injury and suspension, he could still have a role to play with them. Or if not, they'd at least look to get a fair chunk of change back on him from another mid>lower Prem club.
