He didn't have a particularly bad season either. Arguably better than Bernardo's, Rodri's, Jack's, Mahrez', Cancelo's, Gundo's first seasons with us.
We were in for him last year, Pep is rumoured to have been watching him for some time. He has had very good seasons with Lyon before landing at WH. So I imathere is something there the club are looking at.
I would be much more comfortable with that, i.e a very good and proven player that has had an average season, than an average unproven player, that has had a couple of months of excitement to show (like Mitoma). Although the way things are going, we may end up with both.
