That should be good news, he brings strength to their midfield and can cover for Etuhu when injured. At some point, if worked around, he and Murphy could have a good midfield partnership - just like how Etuhu and Murphy do.
Different type of player to Murphy and Etuhu because he can get up and down the pitch, not as good technically as Murphy but far more energetic, offers more in the opposing half of the pitch where Dickson is poor. Glad we've got him.
