Yes he has a bit but did he start Spence v cov? No. He only came on when destiny got injured. Add in that Spence and reg arnt even in the EL squad so cannot rotate much there with FBs.
Ok so he didn't rptate everyone.....but he did rotate. There is proof.
No manager goes into cup games and plays 11 different players to the league.... you're asking for something that is unrealistic in that sense, and he even still did rotate in terms of playing different first team defenders in every game I listed.
