How did you get round the Under 23 rule? It fucked me off, brought some players in, got my squad sorted and then when I was about to start the first game it told me I'm only allowed 4 (I think it was) players over the age of 23
What league you thinking about? Aston Villa and Watford have been my best ones on FM13. Palace, Ajax, Everton, PSG, Swansea and Southampton are decent ones too.
The under 23 rule is only for the Prince Blah Blah cup. Game's supposed to pull the reserve team but doesn't.
