He didn't provide what the manager needed and sold our best player. For me the board are the problem at Everton and have been for 20 years. No manager can flourish under this regime where your best striker is sold for 90m and all they get in through the door as a replacement is a 5m punt
He didn't exactly sell our best player out from under the managers nose now did he ( remember Ferguson to Newcastle )
Lukaku wanted to go , said he was going , his snake agent had it all set up for him and Pogba to become rimming partners so he had to go.
Koeman knew this and got the money to spend and more.
Maybe Koeman should have made a striker his first priority but maybe he didn't want to be dependent on one player to provide goals
Where would we have been if Rom got injured last Sept and was out for 6 months
