Despite what the BBC article says his contract runs out next summer not this one.

Besides which, he's really not that good. L1 goals mean naff all, look at McPhee, Abbott, Elliott, Paynter, Rhodes, Lambert (going to Southampton because no CCC club went for him), Cox, Sharp, Constantine, Eastwood, Hayter, Sam Parkin, Adam Boyd, Knight. They've all scored over 20 goals in a 3rd tier season in the last 8 or 9 years. Have any of them even looked like scoring regularly in th Championship? Eastwood had a good start but has gone flat since then.
Where it matters, last season McLean scored 8 in 39 when their fans said he was carrying an injury. In the same team in the same season without carrying an injury Mackail-Smith only scored 11 in 47. Hardly a big improvement.
