Yes, Nacho's touch was letting him down and he gave the ball away on one too many occasions BUT he seems to have the knack of bundling the ball in somehow at the moment. Personally, I'd have stuck with him into the 2nd half.
The thing that baffles me most was why Rodgers felt the need to change anything at all. I mean, we all have opinions as to what changes we'd make (and mine are invariably comical) but there seems to be a consensus amongst us armchair experts that no changes were needed. Certainly, I thought we were doing just fine. I'd have given it another 10 or 15... our maybe that's just hindsight talking. I feel Rodgers was trying to be preemptive, to predict a Bournemouth change, and that puzzles me. We were controlling the match, we weren't top gear but they were pants. The changes Rodgers made invited Bournemouth on, and that's just what they wanted. Bizarre, even after (I think) trying to adjust for hindsight.
