Portsmouth manager Danny Cowley
Going in 2-0 down at the break after goals from Mo Eisa and a thunderbolt from Theo Corbeanu, Portsmouth responded with a determined second-half showing, but could only pull a single goal back through George Hirst on the hour-mark.
Speaking afterwards, Cowley said: “We’re disappointed about the result, but there was a lot to like about the performance.
“For the first 20 minutes we dominated against a good MK Dons - probably creating three or four good opportunities.
“I think it’s fair for people to be critical of our final action. We need to be more clinical and ruthless in that moment.
“They scored the first time they’d been in our half, let alone their penalty area. I was disappointed with the way we responded to that.
“You can’t play as well as we did for 20 minutes, have one moment of disappointment and let it affect you that much.
“It’s happened a few times here when we concede. It seems to hit the players hard and we have to try to navigate through that period more effectively.
“I thought in the second half we dominated possession and territory, something like 22 shots, got to the final third time and time again - but we lacked a bit of quality. People will criticise us for that - and that’s fair.”
