With all football teams you have to compromise as rarely does the perfect footballer come along.
There has been a lot of simple analysis with the arguments raging like Aguero would have finished those Raheem chances etc but in reality Aguero would probably not have so easily gotten into those positions or dragged Uniteds defence around so much that on two occasions we had a player rampaging through the centre of the pitch.
Similarly again if you asked me who was the better finisher between Sane and Sterling without hesitation I would say Sane.However the stats show Sterling is way ahead of Sane in the scoring charts so its clear Sterling ‘arrives’ in the position to score with more frequency. So do we then have to accept he may miss them, but at least he is getting into those positions, or swap him for a player who is a better finisher, rarely misses, but rarely gets in the right position?. These are the compromises a manager and fans have to make.
It is a similar story with the centre halves. Otamendi and Stones defensively are not the greatest but actually help us defensively by being so effective on the ball, which allows us to dominate posession of the ball and so we do not come under significant pressure. We may find we could end up with better ‘defenders’ but who are not great in posession and so result in us being less effective going forward, controlling games and result in the team having to defend more which may result in the same number of goals being conceded.
The challenge for Pep is to determine if those shortcomings are so great he needs to bring in better defenders of goalscoring wingers, to strengthen the side, or stay with players he has and work on them to improve those aspects of the game and accept there failings on occasions. Because regardless of who he brings in they will also have failings as players and so as one problem closes another is likely to surface.
