Lopes didn't play much because he had the u20 World cup already this summer.I'm disappointed in the random way they were used pre season. I wish we would have put out some balanced sides, & had a serious look at how some of the kids performed under those circumstances. Denayer has had a bit of a sensible workout, & to a lesser extent Kelechi, but the rest have just been fucked about.
I expect we are about to sign DeBruyne, but I would love to have seen how Marcos Lopes looked doing his job, in a strong, balanced side, just in case, or even as an alternative.
I disagree with your idea that they've been used randomly. Garcia got a lot of good minutes in solid teams. Iheanacho played 5 games, with some of our strongest line ups, and Denayer got tried out next to Kompany and Mangala.
Not sure how else you expect Pellegrini to play them.
