Bought my 1st scouts last season (L3) when I got the hang of farming tokens so I've still got last season's pair, and 2 more bough this season.

Matusik, Level 3, n/a, DC/DL, Defensive Wall, 4-5-1V or 4-4-2, DC(left), generally seems decent - consistently rates 7 or 8
Hudak, Level 3, n/a, DC/DMC, Penalty Kick taker, 4-5-1V or 4-4-2, DC(R), generally seems decent - consistently rates 7 or 8 though isn't that great at taking penalties
Yeboah, Level 4, n/a, GK, Penalty Kick Stopper, 4-5-1V or 4-4-2, n/a, has only let in 1 goal in 9 matches (he's mostly playing Cup/CL as my league is seriously lacking in quality this season)
Osinski, Level 4 , MC, Penalty Kick taker, 4-5-1V or 4-4-, L, Superstar (ok, he's already up to 7 stars, leads the league for assists, 2nd equal in the league for goals scored. In 13 matches (incl. about 4 or 5 league matches where he's played 20-30 mins in the 2nd half off the bench) his stats are: Cup played 3, 2 assists, 6 goals, CL played 3, 2 assists, 2 goals and League played 7, 6 assists and 6 goals
