It appears that Pep wanted everybody who was surplus, cleared out of the dressing room ASAP. All who remain, know who is charge if they did not know before. Tixki has obliged and cleared players out. Pep now has his squad. Fullbacks in future Windows may be reviewed and some who were reprieved this time round, may be on their way in 12 months.
Questions remain.
Who sanctioned the purchase of Mangala at that price?
Why did Bony, prolific at Swansea, fall short at City?
Why did Joe play immaculately - short balls - in his final game, yet in the friendly with Arsenal hit his first two balls long?
Joe didn't hit his first one long, the first pass he played was to Fernando in the right full back position.
