Very. He's playing a dutch style of football that doesn't work anywhere outside of the netherlands. You won't win games by firing in crosses all the time unless you have players like Ronaldo and Messi crossing the ball. He doesn't care about midfield creativity.. I mean ffs he's putting Cleverly and Barry out together. The guy has, is and always will be an ordinary manager outside of the Netherlands.
Look at his managerial statistics. One thing that is noticeable outside of the Netherlands is his lack of ability to get teams to score goals. In 194 games his teams have scored 269 goals. That's pretty shit.
Imo you need more scoring options. You have a great centre forward but so do the 6 clubs above you.
Ibra, Costa, Kun, Sanchez, Kane, Firmino/Sturridge.
What those other sides have is more avenues to score goals. The calibre of players needed may not be in reach without European football (unless you offer large wages). Coutinho, Lallana, Hazard, Pedro, Ozil, Eriksen, Alli, KDB, Silva, Mata, Martial, Pogba are all players who play directly behind or beside their striker, this calibre of player Everton don't presently have imo. What do you intend to use Barkley as a no8 or a no10?
Your defence is decent enough and Gueye may be the signing of the summer, wanted him if we didn't get Wanyama. Very good DM.
You're entitled to your opinion on Koeman, this is your thread but 2c from the outside when Koeman at Soton had some good attacking options (albeit a lesser striker) he achieved decent results. Tadic, Pelle, Mane, Austin and Long are decent options in lieu of a top striker, that group of players under his tutelage had wins over Spurs, Arsenal (plural), Utd, Liverpool (plural) and Chelsea. Not bad.
With those players he achieved 1.5 goals a game in the league, that'd net 57 goals a season. Last time you made Europe (13/14) you scored 61 and we also made it with 55 goals.
As I said, you're entitled to your opinion on RK, he's your manager, not mine. That said wouldn't you at least concede he may need to clear out some "deadwood" and recruit some more attacking options?
Probably need a collective upgrade on Deulofeu, Lennon, Mirallas and Bolasie. Only one of them he bought. Maybe another summer window before you can judge him properly? Let him assemble a squad of his own. We were not great whilst Poch had our dead weight but much better with
his squad.
A good signing for you would be Schneiderlin, at Soton he worked well alongside a DM (Gueye) and could again do that for you. Depay is a bit meh though. Big opinion of himself.
