i bought a 28 or 29 yr old dl for for 65mil! he was probably the best in the game and i thought he would really suit my tactic, and generally i try to have the worlds best for each position.
i had actually owned him a few years earlier, but there wasnt really space in my side and he didnt suit my tactic at the time so well, so i sold him for 10mil without a sell on fee, doh!
i would happily spend any amount of money on a player if i decide i want him, e.g i just spent 39 mil on a 29yr old striker. he had been top scorer in the
prem, was very fast, and i wanted to have a 'try' with him before his legs went. I reckon he will probably have a couple of years at the club at the most.
that being said i generally have managed my transfer extremely well, i have made west ham the richest club in the world ~2bn fortune! (with no cheating- i am on a mac we have no fmm etc) This means i can afford to be extravagant when i want to.
