Pochettino says he's considering at least 40 names for the final 26-man roster this summer. The USA were beaten 2-0 by Portugal and 5-2 by Belgium in their two friendlies this international week. "It is going to be painful because that process… is going to be difficult to pick only 26 from 35, 40," said Pochettino. "Who will be there is going to be happy, who is not on the roster is going to be sad." He added: "An end of our cycle... for preparation for the World Cup. I think this is the end because the next roster is going to be the roster that is going to be involved. I think it's too many things that we need to assess and to see in the next few weeks. "I think for sure Belgium and Portugal have in the top 100 players, a few or some playing in that top 100. I think we don’t have." On skipper and AC Milan star Christian Pulisic's lack of goalscoring form at this level, Pochettino added: "Yes, he feels frustrated, but that is what we want, what we expect. "He was fighting... he's going to score because he has quality. I am sure that he's going to come back to his club and the moment that he scores, he is going to score again."
