With regards to Man City, I usually play Liverpool but played a Man City game for the same reason. They're predicted 14th I think, but a few good signings (Enyeama, Skjelbred, Cardenas for me), they can be good UEFA cup challengers at least. They've got a fair defense with Dunne and Richards (and Distin depending on the update), fair midfield with Barton, Dabo and Hamann, and Samaras isn't a bad target man by any means.
Also, if you can do well for around 2 or 3 seasons, players like Sturridge and Miller should start to come good too.
Can't say I know too much about Boro though, other than the obvious stand-out players (Yakubu, Downing ect.)
