I don't think there will be a first team as such, maybe the exception being Benteke and Guzan. I think players will be rested and most will be involved. I don't think you will see anyone frozen out our being a permanent sub
The way that we finished last season, it should be up to the new signings to play themselves into the team through looking good in training, sub appearances etc. The one exception I might make to that is Okore in central defence. It's the one area where we still obviously had issues at the end of the season.
guaranteed for me - end of season form Guzan Lowton Okore Vlarr Westwood Benteke there is only one way to find out for the rest - fight
