Pep bought him as a preparation for the long term project. Pep has a short and long term vision and this is also the main reason to say that if manchester city tries to prepare good player who can play in the club for long term.
His fees is quite expensive but im sure that he will paid off it caused by pep will be ready to develop him to be even better than before. It's just matter of time till we will be seeing his debut with the main squad of manchester city.
In fact, I am the opposite of your prediction, that Aston Villa will likely be able to become champions this season, with such consistent play, it seems that it is not impossible for me, anyone has the right to become champion even though Aston Villa is only underestimated, in fact they have arrived. currently still in second place in the Premier League standings, this makes my confidence in Aston Villa to become champions this season very big..
