Excel Footy Manager
Downloaded this ages ago but only remembered I had it recently. You can play an entire season in half an hour or so and but & sell players any time. I'm playing as Liverpool, currently 4th in the Championship having started in League 2.
It's donkeys years old but good fun.
My current team:
A Niemi
P Mitchell (?) - A Ferdinand - C Riggott - D Gabbidon
A Pang (?) - C Hignett - G Boateng - V Smicer
D Vassel - A Smith
