His point about the "small squad" is that if you have people like Deulofeu/Arda Turan/Denis/Gomes/Rafinha/Paco then it is very difficult to field our best youngsters like Arnaiz or Alena. Instead we should have benchplayers who are stars and youngsters. Wouldn't you agree with that? He had Deulofeu, Vidal and Arda as his main winger-option for half a season - how about that! That is pure crap, there is no Bale on the bench, and that need to change - he would be the first to demand better players on the bench and to slash the dead-weight. And man does he get much shit over Gomes. I'm not even sure he wants him to stay. He played 2 full league games all season, the rest was subs, and yet it is treated like he hates Denis and loves Gomes, even though they have played the same amount (and both proven themselves to be too bad for barca!).
First step is to get Griezmann, which leaves us with class options up front. Next step is to get another midfielder, and after selling the dead-weight (loaning + paying wages, who are we kidding), I'm sure he would like more and better options in there as well.
