3. Pablo Hernandez
The Expectation The Spaniard didn't exactly set the Premier League alight last year, scoring 3 goals in 30 league appearances and sitting in 8th place in Swansea's own player league (according to the Metro stats.) He came at a big cost to Swansea (at £5.5m he was their record signing) but a comparatively quiet season meant his value was at £6 to start the season, not low enough to earn him a place alongside 2 or 3 top level prices (had he been £5, that's exactly what he would have been) and not high enough to draw any attention.
The Problem Right now, the cheap midfielder is performing out of his skin, sitting in second place of the Premier League's rankings behind only Yaya Toure, who cost a relatively huge £2.6 more. In the context of the game, that sort of price difference is massive, and if Pablo continues this form into the rest of the season, his price tag will look like one of the bargains of the year. That causes a problem, since Pablo will have been on very few radars ahead of the season, and could genuinely pose a threat to the top of the leaderboards, just as team-mate Michu unexpectedly did last year. After all, Michael Laudrup's success at Swansea has been built on a strong foundation of fitness, hard-work and consistency.
