Keep him for another season at least. I bought 2 scouts about 5 or 6 seasons ago (MC and DC/DMC) and they both did crap (ratings of 4-5 but I spent tokens on them so was willing to wait and see) that 1st year. After that they performed great - only just sold my MC this season due to age and no chance of making him 6*. The DC/DMC is still my best defender (still 6* though now 27 years old) and is now achieved the most games ever for me (over 145).
