I dont agree with that personally i think he has been let down by the club, look our peers say Utd, Arsenal and Chelsea were all given the opportunity to sign a striker, Lukaku, Laczette and Morata.
I dont see another manager changing the basic underlying problem.
If we had signed any of those we are a different team and Koeman is a good manager again. Its that simple really.
I said at time it was the height of idiocy selling Lukaku its, proven to be the case, it was utter luancay and probably the most stupid decision in Everton PL history not to sign any striker.
What did people expect to happen.
I dont blame Koeman at all.
We are not a bad team, we are a team with no striker.
