Looking at what's happened to Bayern it's made me realise I wouldn't want a Lewandowski/Kane type situation at United. I'd obviously want both players at the club but they both demand to play that much it's almost impossible to sign a decent understudy who will happily sit out every match.
The main issue with that is if they get injured you left with a replacement that isn't good enough.
Bayern were out when it was confirm Lewandowski was injured for both ties.
No. The biggest problem was the pile of injuries that piled up in the recent weeks and that some players like Kimmich and Müller had to go every minute between the matches - and you cannot expect them to go full workrate in all this matches but at the end be the ones that have the energy to be decisive, too. Lewy was not too decisive in the recent years either in this matches - he was very valuable as he attracts the defenders more than his replacement does but he has as many goals sind 2010/11 from quarter final onwards as Müller has.
Just as an example: Somebody has posted the top running data in the EPL of last season in a recent post - best was 13.21 km of Dendocker in a Wolves-Brighton match with 13.21km - rank 7th were 12,79. Kimmich ran 13.1 in the match against Leipzig and 12.9 km against Union Berlin last Saturday in between the PSG matches. In the first PSG match he did 38 pressings what tells about the intensity, too.
Lewy is a miss, yes, but Gnabry who recently got back his shooting boots again is, too - and when we have 3 wingers available Flick can rotate and give everybody a rest. Goretzka has been a standout offensively as well as defensively - he is more a goal threat whereas Kimmich is the creative mind in central midfield.
In this matches you need to be 100% - the last years have told us that. The injury situation in the recent days I have seen this extent in the last time in 2014/15 when we went out against Barcelona.
The whole situation and schedule of this season did not really benefit the club and there were made mistakes in the whole squad planning. Flick never had a real preparation and that already showed last season when we benefitted a lot from a skeleton that mainly was build from players that still were Pep kids and the structures they learned. We always got in trouble when players of this central axis could not play or were substituted. Selling Thiago without need in that situation, getting players very late so there were never really a time to build them in etc.
