We've all heard of "second-season syndrome," the manufactured condition by which a player is sussed out following a solid debut campaign. Their second campaign, as a result, is not as fruitful.
The decline of Everton's Nikica Jelavic in the season just gone is perhaps the most recent pertinent example. But he is not the first and certainly won't be the last to fall foul to it. The Premier League has proved to be a difficult environment in which to maintain a consistently high standard.
But some players come in, start well and build on their initial showing.
Last season in particular, there was a host of players who adapted well in their maiden Premier League outings. And whilst some of these players may not have as significant an impact next time around, others will learn, develop and ultimately improve when they get their second bite of the cherry.
With this in mind, I've picked out five players who you would expect to build on their solid debut seasons and become stars in next season's campaign.
