Boss: On-loan defender can improve

Shackell, 25, arrived on loan from Wolves in mid-August and the two clubs have agreed to extend the agreement until January.O'Driscoll told the Sheffield Star: "I think that he's got a lot of good attributes in his game, but I also think that he's got one or two things that he needs to work on."They are probably the things that Wolves boss Mick McCarthy sees in him and that's why he feels that he can't play him in his side."Jason is prepared to work on things to improve his game and he responds to positive criticism really well."With him being here until January, it gives us the chance to try to mould him into a better player."
