This isn't exactly accurate. Pogba plays for Manchester United, Mendy plays for City, Kante and Giroud play for Chelsea, Lloris keeps for Tottenham. The two teams in the third place match Saturday could nearly field a starting 11 made of just United and Tottenham players. Heck, Kane won the Boot this year.
The EPL has some of the richest teams in Europe. They struggle for two big reasons. They don't get the midwinter break that other leagues get, and the league is more competitive as of late.
