Whilst I understand the benefits of a small squad going into a season without many variables (I personally think Pep has simply stated he prefers working with a small squad for PR purposes, as what manager doesn't like working with as many resources available to him or her) I do think its unwise not to air on the side of caution going into a unprecedented season where a winter World Cup takes place & inevitably further injuries will be picked up. Whats worked to our benefit in previous seasons is our squad depth, whilst others may have a competitive first 11 the injuries & fatigue take their toll during the 'business end of the season' & do not have the depth to compete at the same level.
I disagree with top players being more open to move in January. Usually its the top players who are more settled during this time & are less likely to move due to relocating family etc within a short time frame compared to the summer window. Its more likely to be the 'desperate' players who want a Jan move or the WC starlets who play a blinder during this particular month & artificially inflate their profile & transfer fee. I would have hoped City's scouting board is more adept at recruitment than waiting for someone to perform for one month during a World Cup & only then striking to acquire where it then naturally becomes a seller's market. James Rodriguez & Andrey Arshavin spring to mind after having successful high profile tournaments.
