By point of comparison - how much are Fabregas, Coutinho, Mata, Cazorla, Oscar etc earning? Eriksen was better than all of them last season. Let's not even talk about Wayne Rooney who is earning about double what Eriksen is allegedly demanding. While I don't think anyone would argue that he's better than an an in-form Ozil or Silva, what you need to consider is market rate for a player of his ilk. When you've got Liverpool chucking £100k+ salaries to players like Jordan Henderson and James Milner...well, Eriksen and his agent will notice that.
6 goals + 16 assists = 22 league goals he had a hand in last season. Not even Modric or Van Der Vaart had that kind of output for us, and Rafa took our penalties which Eriksen doesn't. I don't have the "chances created" stat to hand but I believe he was second only to Ozil last season. The fact is, the guy is a proven Premier League performer, who at the age of 24 has more international caps than Paul Gascoigne or Glenn Hoddle ever got. I don't really see what justification you've got for paying some of the players I mentioned above £100k+ salaries whereas Eriksen apparently needs to be content with so much less even though we're in the Champions League (and we wouldn't be there if it wasn't for him). It's not just one or two rare exceptions, the going rate for a half-decent attacking midfielder in the Premier League seems to be around the £100k mark at least these days.
Dier and Alli could turn out to be one season wonders. Eriksen has completed three, each better than the last. He is probably our most gifted player technically. £150k perhaps seems a little excessive but if there's anyone in our squad who should be earning £100k+ at this moment in time then it's him.
