Would give Walker a break right now actually. We can play Bolton against Burton and Danilo can play Burnley and Newcastle.
Think players usually get at least one day off a week maybe 2?? Give Walker an extra 2-3 days and let him fly to Dubai with the wife and kids to relax the mind like you suggested.
Don’t think a 7-10 day break is realistic during the season but right now while we are in a good position fixture wise, Walker can take 4 days off for example. Wed to Sat back in training on Sunday and on the bench at Newcastle for example. Of course he could train alone in Dubai as well.
I still doubt something like this will happen but Pep should definitely consider it. He suffering from mental fatigue not physical but the mind effects the body clearly.
He's got to be suffering from mental and physical fatigue. I checked and he's played more games than anyone else, more minutes than anyone else and more 90 minute games than anyone else since he arrived.
No rest after the world cup, not even rotation because Danilo was injured.
I would send him away for a few days and I'd also advise he gets one of those 10 day injuries during the next international break, he is going to start for Southgate in the games that matter - no debat about that, only whether he'll be RCB in a 3 or RB in a 4.
