It seems to me that computer clubs don't buy any new players, even when there are obvious flaws in their team, and they are underperforming. This is true even when they're swimming in cash. Man u on my game finished 8th in the first season (Ronaldo + rooney cruciate ligaments- what luck!!!), however they didn't buy anyone in the transfer window. 4 seasons later, they've only sold players, playing very old current players, like Neville, or terrible youngsters. When I added new manager to check how much cash they had, transfer budget was 150, with wage difference of 700k!
