1. There are loads to choose from. They have all got different rules, so remember to read them all before entering. some like the metro, channel 4, sky sports, the times are free, while for The Sun, the telegraph the prizes are much bigger/better, but you are paying to enter!
2. It depends on which Comp you are entering. In general look at players newly transfered in, either from abroad, or weaker premiership teams, e.g.
Baines will look good once his move to Everton is finalised. Tevez likewise, though he could get rotated by Fergie.
I tend to stay clear mostly of Liverpool, Chelsea players just for the fact that their managers like to rotate their team around.
This season I will be entering a couple of teams in the Sundreamteam, a couple in the telegraph, and I have one already entered on the "Premier League" website! I might try out "The Times" new game, though it looks a tad complicated!

I will also enter a team on the Sky Sports website. It is the original Fantasy Football, though your captain scores you double points! (it is free to enter as well)
