SWINDON Town boss Michael Flynn says his side "must improve" defensively after the 4-0 League Two thumping at AFC Wimbledon on Saturday.

The Robins have now conceded 40 goals in their 21 league games so far and is a total only exceeded by Sutton and Colchester, who are in the bottom three of the table.

"We were very poor defensively and I don’t mean just the defenders," said Flynn. 

“We’ve conceded 40 goals now in the league, which is way too much – some teams will go through the season probably conceding that many.

“We’ve got to improve and I’ve got to improve in that area, which is what I’ll be looking to do.

“The second goal, they don’t even sense there’s danger from the free-kick, everybody’s switched off.

“The first goal shouldn’t have been allowed because there were two down with a head injury for over 10-15 seconds and the fourth official was telling the referee.

“It’s a diabolical decision for him to play on there because it’s the safety of the players, but we weren’t good enough today and that was only one goal.”

Flying out of the traps brought reward for Wimbledon after just six minutes when Omar Bugiel turned in Joe Lewis’ cross from close range.

The hosts really pressed on after doubling their lead in the 59th minute through a stunning long-range strike into the top corner by Armani Little.

Dons top-scorer Ali Al-Hamadi then took advantage of the widening gaps in Swindon’s defence by producing two clinical finishes in the closing stages, which delighted Dons' manager Johnnie Jackson.

“We spoke a lot about trying to start fast, building on the momentum that we’ve created here," he said.

“Going into the game, we’d won five on the bounce here and it’s become a really difficult place for opponents.

“We wanted to make it uncomfortable for Swindon in the opening exchanges.

“We carried on the work that we’re doing, we doubled down, we worked harder and the lads believe in themselves."
