What on earth are you talking about?
Klopp called the fixture congestion madness. Mourinho called for the league cup to be scrapped to ease the fixtures, the big cheese at City said exactly the same. Can't be sure if Pochettino said similar but he probably did. Those at the top with better players have done well except Arsenal. (Wenger probably feels the same as the above). Not the sole reason for our slump of course, but saying others in Europe are not bothered by the fixtures means you need to read a bit more widely.
Funny isn't it, the managers that are most successful in the cups complaining about fixture congestion. They also have the biggest squads. If they are that pissed off about it go and manage a lower league team who don't have so many fixtures. Oh, see how your salary stacks up them. Moaning twats.
