Milton Keynes Dons were eliminated from the Emirates FA Cup at the Fourth Round after suffering a 1-0 defeat against Coventry City.
Despite the result, Upson is positive about the future under new manager Dan Micciche and Assistant Manager Keith Millen.
“We can take a lot of positives from the defeat,” Upson said in his post-match press conference.
“The manager and Keith have just come in and they’ve given us an identity. They've only been in a few days but you can hopefully see the start of something good.”
The Emirates FA Cup clash also saw the return of Dean Lewington - who featured for the Dons for the first time since early November. Following the full-time whistle, Upson praised the impact Lewington has had on the squad.
“He’s a big character and has done a lot in the game - especially at this Club. He’s a massive boost to our changing room, that’s not just on the pitch but away from it too.”
Upson did, however, admit that the Dons issue this season has been not converting chances while in control of the game.
“We might get two or three chances and not take them and then we’ll get punished at the other end by a goal that could perhaps be avoided - that’s probably been the story of our season.
“We need to cut it out, I know we’ve said that a lot, but I really believe in this manager and Keith - I think we can really turn it around.”
Despite sitting in 21st position in the Sky Bet League One table, Upson is confident that there is enough quality within the squad to escape the relegation zone.
“When I look around the dressing room I feel like we’ve got a team that should be way up the league.
“At some point, it has to click, I really believe that with this new pair, it will click. We’ve got the players here to play the style of play we are looking to go for and a style the fans can relate too.”
