We brought in 4.
We lost 7, from what we went into last season with.
Excluding kids, which we also lost a fair few of that had the odd bit of involvement around the first team.
This indicates two things:
1. We are likely to sign other players.
2. Pep takes the option for 5 subs in a completely different way than many on here, namely as an opportunity to cope with a smaller squad than when the rule allowed 3 subs.
