I'm with PB on the subject of Aguero. Looks like a man on borrowed time to me and today he was absolute wank. Chuck in 7 games out of contention due to self indulgent petulance, at a rough cost of £1.5m in wages, and I can't see Pep putting up with him long term. He needs a fucking rocket up his arse. I'd disagree with your assessment of Sterling's contribution however. For the first hour he was diabolical, a walking dictionary definition of how not to deal with a baying mob. He ended up losing the ball every time he tried to run forward, he crossed it into the crowd, and ended up playing the ball backwards time after time. He improved thereafter, but was still no more than a 4/10 overall.
As others have said, calls for Pep's head, or anything of that nature, are ridiculous. There's no point in acquiring the best manager in the world and then not giving him time to do the job, and if you compare the 2nd half today to our performance at Klanfield 12 months ago, then you'll see clear evidence of our improvement. The sense of disappointment should not be ignored however. When players like DeBruyne, Aguero, Otamendi and Sterling turn in performances as gormless and physically and mentally weak as they did today, it's not unreasonable to ask why the manager isn't getting more out of them. What irked most was that the candle wavers were there for the taking today, and we still didn't look like turning them over. There's an almighty clear out needed this summer IMO and the time to start judging Pep properly will be in 12 months time
