Agree completely. I would love to see us integrate some younger players to help the burden. I don't think throwing one or two in would make much difference and will help with the number of games we have and the lack of recovery time. The younger players will recover far quicker. This season should be sacking the league cup off really, but Pep just will not do it. He wants to win everything, but I think it hurts us when it comes to the Champions League knockouts.
The way we're playing this season we're also not really controlling games and so the amount of running will be a lot higher. Usually we'd punish teams early and then pass it around and manage the game. We seem to have lost that and end up in this end to end counter attacking football which requires effort right to the end of the match. At least in the CL you can still make the 5 subs. And hopefully game management improves as we get into the season. A lot of poor passing and mistakes throughout the side so far.
