I don't quiet understand the comparison. Despite being similar, these players are quiet different.
Both of them are basically a better version of Juan Mata.
Bruno is Juan Mata with more pace, grit, attitude and workrate, but less technique and finess.
Eriksen is basically Juan Mata with the same technique, finess and vision, slightly faster with more workrate, but still less than Bruno.
While being similar, these 2 are still different players.
The only reason Eriksen is rated so highly is because he didn't play for us. I already see how the caf would react when he attempts a through ball, losses possession and just site there and jogs back a la Pogba. This place would eat him for breakfast, lunch and dinner. For those of you wondering what I'm talking about, this season he has a 74.4% pass completion rate, where Bruno has 75%. And Bruno is supposed to have a mare of a season.
