United were toothless and we had them on a plate for the taking. He played it second half with a pop gun counter attacking unit, not committing bodies to attack in sufficient numbers. Then he loses his nerve and takes off two players in Mirallas and Barkley who were occupying United and putting a shift in.
Never mind agendas and 60 seconds from "unqualified success", Koeman ballsed that up.
He likes to present himself as a top manager (and the gullible fall for it) but he's miles off, and the tactical errors he's made this season at key moments underlines just how bang average this feller really is.
He's got a long way to go to be among the elite, but he's certainly better than the rest currently operating in the Prem and that is reflected by our current league position, which was the target since the very beginning - to get back to the top seven and hopefully secure Europa League at the least.
We haven't got the squad yet to challenge for the top four and yes, Koeman has made mistakes at times - i.e. Calvert-Lewin last night.
The Mirallas sub was probably a bit too early but that change saw us switch systems and Pennington did well.
Barkley was flagging and had to go off but DCL shouldn't have been the player coming on.
