Actually can't remember anymore. A basic of £8m is ridiculously high though. I'd love if that was true. That could bring the total income from players' sales for that season to over £15m (£10m Ulloa, £3m Bridcutt, £2m Buckley, +Barnes) although that £8m basic should be taken with a pinch of salt...
I heard it was something similar to:
£6m, and then £1m if they stay up, £1m if Ulloa scores a certain # of goals. It might be wrong, but it sounds plausible, and takes us to the £8m quoted figure. I'd imagine 12 goals is the limit, as expected 15 goals from a bottom 3 striker is quite a stretch.
