Andreas Hinkel has been brilliant at RB for me with Leeds so far! although wages are quite high for championship (17k) he will also easily cope in a mid-low table prem team, so no need to replace after promotion!
Grab Danny Rose and Paul Pogba on loan! Immense for me in my 1st season as Brighton. Some decent freebies too. If your a top championship club like west ham you can get McFadden. Materazzi is a good solid backup as is Parnaby.
Definatley suggest Hinkel and Parnaby (Both free Rb's but better than my Current Leeds United one. Connelly)
Stephen Hughes on a Free, again a good strong player with experience (DM)
Grant Leadbitter from Ipswich, if signed will lead your midfield through the championship, and playable at lower PL. However will cost you upwards of around 2M, and similarly Jordan Rhodes (Huddersfield ST), a great young player with potential for Championship superstar status. However Greedy town want around 4M for his services. Though, in my game he isnt happy at town due to poor season and is looking for a move. Possibly a cheaper buy.
Agreed with Saulabbis, Danny Haynes, scored 10 in his first 11 games for me. Pretty cheap as well.
Finally, if wages arnt an issue, James McFadden. Best LM in Championship by a country mile, and will be a good PL player too. (Free Transfer)..
