Martin O Neil has built a decent looking squad for Sunderland, i think they will definitely finish in the top 10 this season. Their midfield and attack look good. and with O Neil's ability to make a team well organized, even if they do not have very good quality individually in defense, i'm sure he's going to make them rock solid.
Fletcher and Adam Johnson are great signings for them, both are starting today against Swansea. Sessegnon is a player i like very much, and Mclean looks quite promising too.
