I sold a near-exact same player. 6 in tackling, 19, left footed, English, 3 in passing, and 1 and 2 in the other attributes. £323,000. I wasn't complaining. I stuck him up at £200,000, expecting not to get a bid, but I was pleasantly surprised.
I've just sold a 20 year old 4 ball keeper for £100,000. I can't wait until the poor sod discovers he is maxed.
