Birmingham boss Alex McLeish believes new signing Barry Ferguson will have "something to prove" when he returns to the Barclays Premier League.
City signed the 31-year-old from Rangers for an undisclosed fee in the region of £1.2million - on a three-year contract - as he makes his return to England for the first time since an injury-plagued spell at Blackburn which ended in 2005.
McLeish told Rangers official website: "Barry has played at a very high level for Rangers, in big games. Maybe the Scottish league is not the strongest but he's played a good level of games, in the Champions League, the Celtic fixture and cup finals. I think he has got unfinished business in England."
He added: "He started with a bad injury at Blackburn, then fought his way back to fitness, and the reports I got at that time, before he came back to Rangers, was that he was playing extremely well.
"But maybe he didn't stay long enough for people to make a full assessment of him. So I think in that respect Barry will want to come down with something to prove.
"They have barely started pre-season training but again, from the reports I've had, he's been up there in the fitness testing they have done. He's always been a pretty fit guy."
