I think he might have made a big difference.
But he might have made no difference at all. He would be a new player at a different club.
Arsenal do not face the same level of concentration City do, anymore & haven't for years. It's easier for individual players to shine.
I've posted all along I didn't especially want him because I think Jesus, Sané Sterling & kids have to play more games if he's not here & the manager has to work harder at improving them.
If this squad isn't good enough to compete, in Pep's 2nd season, then it's his fault imo. I don't think Sanchez is good enough that we would just ahtomatically dominate. Pep should have this team right up there. With a view to wiping everyone out in the coming years.
That doesn't mean I'd necessarily want to sack Pep if it didn't work out short term, just that he would need to do better. I'd like him here for years, building.
But City should be right up there, with or without Sanchez imo. We have the players & the goals are already there uf we find the right method . If the manager earns his crust, he will get them scoring.
