I think Jones and Bent are underrated, so on my sunderland save a while ago, i bought kikin fonseca and played him on his own as a target man, he was great.
I'd go for Bent and Campbell... Bent as a ATT target man and put campbell as poacher. campbell might take half the season to start producing, but once u get the chemistry going, your in for goals.. I had bent win the league TOP scorer in first season and Campbell won the 2nd year best english player and scorer and euro golden boot.
But u will need to bring in some good AM. try Di maria , he is available for reasonable pricing. Also Jonjo Shelvey at AMC is very good for a 18 year old kid. Get yourself Kryvtsov for DC and your good to go
