Milton Keynes Dons goalkeeper David Martin received his manager's backing after gifting Bradford City a 1-0 win, their second home victory inside a week.

Martin, son of former England defender Alvin Martin, swung his boot at fresh air in the 71st minute, leaving Bradford striker James Hanson an unguarded net for his 10th goal of the season.

It was rough justice on the Dons, who had most of the possession in the second half but failed to make it count.

Boss Karl Robinson said: "You can't legislate for that.

"David made a mistake, but I am not pointing a finger at him. It was an error of judgment but he has been magnificent this season.

"He bounced back in the right way by making a great save after his mistake. He will get over this quickly because he has been brought up in the football industry.

"His father is very honest with him and I couldn't wish for a better goalkeeper."

Robinson added: "Tactically we got it right and played the better football.

"I thought we were much the better side, though I have immense respect for Phil Parkinson and his Bradford team.

"For the first 20 minutes of the second half we got into some great areas and didn't score so I am frustrated.

"We deserved a lot more than we got so I am sick and gutted. We really dug in but we are just not taking our chances."

Parkinson was delighted with another home win.

He said: "You have to win all types of games and MK Dons came here with an extra man in midfield so we always knew they would have more possession, but we played with a lot of discipline.

"We have scored a lot of goals like that, with our front men pressurising their keeper and back four.

"James Hanson ran himself into the ground for the team and really deserved his goal.

"The way he looks after himself away from here enables him to play like that."

The Dons were so hard-hit by injuries that they named just four substitutes, among them striker or winger Sanmi Odelusi, who signed on loan from Bolton 24 hours earlier and left the bench 11 minutes from the end.

Bradford were indebted to Stephen Darby for a 26th-minute goal-line clearance from Izale McLeod's angled shot, but Hanson was unfortunate twice in a four-minute spell.

First his overhead shot was inches too high. Then he rattled the crossbar from just outside the box.

The Dons dominated for long spells in the second half, with 17-year-old midfielder Dele Alli showing rich promise, but Bradford defenders Stephen Darby and Andrew Davies were outstanding and when Martin made his mistake, Hanson made him pay.
