I didn't remember him at Watford but it is kind of weird that he didn't play more than 200 or so minutes given he managed two assists in that time. Especially when you check out the rest of the team and realize that no attacker outside of Deeney or Ighalo, who started almost every game, did better. Just strange that he never played.
Anyway at 28 there isn't really a point to signing him. His European record down the years suggests he's a classic Dutch League stats compiler.
I dont remember him from Watford, I just saw he played 13 times and was binned off as a matter of urgency.
Of course so was Salah and KDB, but I suspect they are exceptions.
