Birmingham City manager Tony Mowbray is "getting stronger " after an operation.

This is according to his assistant Mark Venus who says the 60-year-old situation is improving.

Former Celtic player and boss Mowbray, who was appointed by the English Championship side last month, was announced as taking a break due to ill health 10 days ago.

And Venus has given an encouraging update on the ex-defender's condition.

He said: "I have had a chat with him every day to be honest. A little update: he's had his surgery and everything's fine.

"He's getting stronger, so he is on the way back hopefully. I'm not saying immediately, but it's been nice hearing him and chatting to him.

"It's given us a bit of confidence. I gave the lads a little update from him this morning (Thursday).

"They all asked, they kept asking. We are keeping everyone up to date with it. He's getting stronger."

Meanwhile, Chris Sutton insists "you don't know which  Celtic team will turn up this season" after the Parkhead side's 7-1 win over Dundee.

The Scottish champions ran out comfortable winners against Tony Docherty's men thanks to goals from Cameron Carter-Vickers, Adam Idah, Matt O'Riley, Daizen Maeda, Greg Taylor, Callum McGregor and Daniel Kelly.

But Sutton says Brendan Rodgers' men cannot get too carried away result and that there is still plenty of football to be played.

Speaking on Sky Sports, he said: "Let’s not get too carried away with that. It was a big night for the goal difference. Rangers one better off are they?

"So it is a big night in that respect. But Rangers getting a win at Rugby Park was massive for them. What a game we have got on Sunday.

"Celtic go to Hearts, and let’s get it right; we don’t know which Celtic team is going to turn up on the evidence of what we’ve seen this season.”
