Don't know whether to cash in on this player or not

[mrcjevans]

ok now there is what 5 games left of the season, this guy is 18, quality 21 which is 5 * as I'm new and this is my first season, his stats are 19.8 23.4 22.4 and his market value is 2.28 million.

I have 556k, 36 tokens, and I'm clear top of my league by 9 points.

Now the question is, do I try and cash in on him now? Or keep him for next season, I have just been training him and another midfielder really hard, his guy was only quality 17 at the start. Sorry for so much text, I went to take a photo but there's no easy SS option on player profiles.

I'm also curious if I'll even need to invest at all next season, here's a pic of the current team http://sphotos-h.ak.fbcdn.net/hphoto...73445921_n.jpg
