Birmingham manager Wayne Rooney is adamant he does not want VAR in the Sky Bet Championship despite his side being denied a clear penalty in their 3-1 defeat by Southampton.

Gavin Bazunu wiped out Oliver Burke just before half-time when the score was 2-0 but referee David Webb waved away the spot-kick shouts.

Instead, Taylor Harwood-Bellis, Carlos Alcaraz and Adam Armstrong’s goals condemned Rooney to his third straight defeat as Blues boss.

“These decisions happen when you don’t have VAR,” said Rooney. “I’m not a fan of VAR and you accept referees and linesmen might make mistakes but what you can’t accept is the penalty decision.

“It is ridiculous and everyone in the stadium could see it.

“The keeper is committed and is coming at pace and is reckless. If he is coming like that then he has to win the ball but he absolutely wipes out Burkey.

“The most frustrating thing is that the fourth official told me that the referee was clear in his decision and wasn’t willing to take advice from his fourth official and assistant.

“He was clear there was minimal contact. That is a worry for me.

“I hope VAR doesn’t filter down but we would have got a penalty if VAR was here.

“I know referees will make mistakes, I can accept that but for me that was too much and a big error.”

Southampton manager Russell Martin agreed, saying: “I haven’t seen it back but at the time I thought it was a penalty.

“I feel for Wayne and if he’s frustrated with that I would be as well.

“It was a moment of madness from Gav. He hadn’t had a lot to do at that point.”

Saints opened the scoring in the ninth minute when Harwood-Bellis nodded in his first goal for the club from Adam Armstrong’s cross.

Alcaraz added a second from close range after fine work from Kamaldeen Sulemana and Stuart Armstrong.

Jay Stansfield wonderfully bent in his fourth goal of the season 52 seconds after coming off the bench but Adam Armstrong settled things with his eighth career goal against Birmingham.

Rooney added: “I thought Southampton were the better team and there are no complaints that they won the game.

“For where we are at, we could have come away from this game with something. There are positives for coming to the best team in the league at playing football but there is still a lot for us to work on.”

It was Southampton’s sixth game unbeaten and Martin said: “It has been a really nice run, especially after the run that came before that.

“That probably makes me more proud of the players and the staff for the way they came through that. It has been beautiful to see the growth in that time.

“To see them smiling together and fighting for each other, it has been brilliant to be a part of it.

“We played some beautiful stuff in the first half with so much energy and aggression, without giving them much threat.

“I’m annoyed we conceded the goal as Gavin deserved a clean sheet.

“We deserved to win and should have scored a few more goals, so there is a bit of frustration but I’m there to be relentless with the lads.

“It has been a brilliant week for us and now we have to keep going.”

Adam Armstrong scored his eighth goal of the season as Southampton eased to a 3-1 Sky Bet Championship victory and condemned Wayne Rooney to a third straight defeat as Birmingham manager.

Forward Armstrong now has eight career goals against Blues, more than he has scored against any other side, as he settled the game with a fine finish.

He had set up Taylor Harwood-Bellis’ opener before Carlos Alcaraz tapped in – both players’ first goals of the season. Jay Stansfield pulled one back for the visitors but it could not help end Rooney’s winless run.

Southampton had monopolised the opening stages without creating anything clear-cut until Harwood-Bellis nodded in the ninth-minute opener.

Armstrongs Stuart and Adam worked a short-corner routine before the latter lifted for the Manchester City loanee to power in his third professional goal, and first since last September.

Blues rallied but Oliver Burke’s lashed effort into the side netting – their only shot of the first half – poked the hosts back into life.

Kamaldeen Sulemana and Stuart Armstrong linked up smartly on the left flank before the Ghanaian slid across the face of the goal for Alcaraz to push in.

Rooney had been booed after Wednesday’s 2-0 home defeat by Hull, and Saints supporters rubbed their advantage in with a round of “sacked in the morning” aimed at the Manchester United great.

But rather than rub further salt into the wound of Rooney’s poor start, Birmingham fans supported their boss with cries of “Rooney, Rooney” and “Wayne Rooney’s Blue Army”.

Their support should have been rewarded with a spot-kick but goalkeeper Gavin Bazunu got away with flattening Burke in the box.

Saints should have gone into the break with more than a two-goal advantage as Harwood-Bellis’ free header from a corner skipped wide and Adam Armstrong clipped a one-on-one over John Ruddy but wide of the goal.

After the break, Stuart Armstrong tamely ended a well-worked move and Adam Armstrong’s diving header flashed wide.

But the hosts floundered and Blues capitalised. Stansfield jumped off the bench, met Lukas Jutkiewicz’s knockdown, bullied his way past Kyle Walker-Peters and rifled into the top corner – all within 52 seconds of his 57th-minute introduction.

It was Stansfield’s fourth goal of the season and extended Southampton’s wait for a home clean sheet to 28 matches.

But Saints held onto the ball well and made sure of the result in the 86th minute when top-scorer Adam Armstrong pounced and swivelled onto Sam Edozie’s nod down.

Scott Hogan curled one onto the roof of the goal in additional time but it could not stop Saints moving to a sixth game unbeaten to cement their place in the play-off spots.
