Yet doesn't make them attractive to arguably their best player to a mid table team in Italy. A poorer league than EPL.
Nor did it make Bilbao a more attractive position to Herrera vs mid table English side.
Of course money is a factor that's one of main points. Money out weighs playing in CL on most part with these players.
Bacca was one of the best, but far from the best... way far. Krychowiak, Pareja, Banega, Vidal and M'bia... these were our true stars in 2014-15.
Also, the Bacca deal was for 30 million euros, his total release clause which no other club paid. Moreover, it included an ease in negotiations for Rami (Lyon were favorites on signing him until the last moment) and we signed him for a low price of 3,5 million.
Bacca was going to leave anyway, and he chose the money, not the club prestige and trophies opportunity. This is something very common of players being 29+. They care about the family and want to make as much money as possible before leaving. That was M'bia's case. But of course not every player is the same.
I wouldn't say that money definitely out weighs playing in CL as to the attraction part. Every component plays its part in the football world. However, first comes business of the clubs, then everything else nowadays.
Also for the 100th time, I hope the British people will understand it once and for all. EPL is a strong marketing brand with the majority of the fan base in Asia, not necessarily a qualitative football league. English national football team speaks for itself.
Oh and Man Utd was mid-table like once in 30 years or something like that, for Liverpool it's not something new.
