Is he on low wages? Do we know that?
Also, who is going to pay even half of what we paid for him?
He looks out of his depth at this level, which means interested clubs are likely going to be clubs who will struggle to afford him. I think we are really going to struggle moving him on because I'm guessing he's on a good top flight level salary on a long term deal.
He'll be on an average PL wage. He's played 100+ top flight games for Burnley before 22. He has lots of scope to improve. Right now...no and he's been poor. But moving him on at some point won't be difficult as he's not on ridiculous wages. What we'd get for him...who knows. One year he could turn into James Rodriguez mark 2...who knows.
Bottom line is that compared to signings like Gomes, Mina, Allan, Sigurdson, Tosun etc where we've spent £30+mill and £100ks a week that we've struggled to shift, a signing like him is easier to manoeuvre.
We signed 8 players. 2 have been underwhelming, 1 hasn't had a chance yet (Garner), the other is a loan (Vinagre). The rest are 1st team regulars. You'll find it difficult to find another club in the league that have signed that many players that have all been superb.
Mistakes get made. The idea the original post made a point about is being able to fix that mistake which previously we couldn't.
