The lure of a big club can be hard to resist for some promising young stars and it's fair to say that more than a few have taken up the offer of more money, prestige and glory too early in their burgeoning careers, only to sink into mediocrity and anonymity all too soon.
However, some stars get it just right and make the step up to one of Europe's bigger sides at just the right time to fully exploit their talents and aid their development on to the next level.
GMS have scoured the leagues of Europe and have picked out five players who are just about ready to make the step up to one of the bigger clubs around the continent.
They are young players but there is no specific limit on the age - at times 'young' can even refer to the stage of development in their career.
Obviously, not everyone will agree with the names put forward, but you can leave a comment below with the players you think should be there.
