Chelsea boss Mauricio Pochettino admits he wants team spirit to develop naturally.
Pochettino was speaking after last night's 1-1 draw with Newcastle in the US.
He said, "It needs to be natural, you cannot force players in free time to go together and share things to do. That is more regular. First of all I think we need to define the squad as I think we are 29 players here and it is massive, the squad. At the moment the dynamic is very good, really good guys and they are sharing the time together. It is difficult because sometimes in every game three, four, five players cannot play and that is difficult because the mood is difficult. It is about creating a squad with good balance and people who have the opportunity to play and can compete for their place.
"That is a big job and challenge for us in the transfer window to build a good relationship and good balance and then okay, if players are not happy because they believe they are not going to play, we are going to find a solution with the club and fix the situation. What we cannot have is a massive squad, players not be involved and then it's going to create a mess in the squad. Maybe less is more and more is less, it is not mathematic.
"That is why I need to make clear we don't need a big squad. We need 22, 23, 24 players with some younger and that's it. I am so sorry because maybe the decision will be tough but we need to build a good and a balanced team who want to compete for things."
