Not a shock really, he happily did it a year ago, even when we had no-one to replace him at the club (remember we had to put Adama at RWB at the start of the season and Buur came on vs Sheff Utd).
My suspicion at the time was that he saw his levels dropping off and he was only ever going to go one way. He isn't going to teach him to defend and he's 30 in January. Finding a taker might be more difficult now everyone has seen how crap he is if you don't play him exactly where we did between 2017 and 2020.
