As i've been saying for seasons now, some people just hate Kolarov for being Kolarov. Excellent performance today, didn't have aan awful lot to do but didn't put a foot wrong and used the ball intelligently. I think we're underestimating just how difficult it is to learn an entirely new position in such a short space of time, especially one as crucial as centre back. Based on that, i'd much rather see Kolarov there than the rash and tactically weak Otamendi, i think even Pep would have a job getting him to stay in position.
