A true hero
Teams: Hull City Tigers
The situation at present is a case of the top teams standing still (or getting slightly worse) and the rest of the league getting a lot better. If you look at the teams that the mid table teams signed from overseas this season compared to the top teams then there isn't really much difference in quality between the players signed by the traditional big 5 (Firmino, De Bruyne, Memphis, Martial, Otamendi, Pedro, Rahman, Schweinsteiger, Darmian) and the teams outside (Shaqiri, Wijnaldum, Imbula, Ayew, Van Dijk, Cabaye, Funes Mori, Payet, Son, Rondon)
To get the gap back, they need to sign the elite players that are bought up by Barca, Real, Bayern and PSG. Unfortunately for them, most players who would make the grade needed are already at those clubs.
Europe wise is a mystery, but when English teams were dominant, Barca were the only real super club and the monopoly of world class players between the big four European teams hadn't really started.
They all need 3+ proper world class players this summer, we will see what happens.
