Dušan Tadić admitted there are plenty of things the team need to improve following the defeat to Manchester United.

Saints were beaten 2-0 at Old Trafford on Friday night, as Zlatan Ibrahimović scored in either half to give the hosts all three points.

Claude Puel's men did manoeuvre themselves into a number of threatening positions during the match, but were unable to translate that into any goals against José Mourinho's side.

Speaking to reporters after the match, Tadić explained that there are a number of things that need sharpening.

"We are disappointed," he said. "We expected a tough match. We had some chances in the first half, maybe we should score, but they scored from one cross – a nice goal from Ibrahimović – then after it was tough for us. We need to see what is good and what is not good and to clean our mistakes.

"I think we need to improve a lot of things. We should play much better. In everything, in defending together, in attacking together. Everyone, we need to be on a better level. In that, I mean first on myself and then everyone, and that's it."

With Saints having been using a diamond midfield formation under Puel, Tadić added that it will take a bit of time before the players are completely comfortable in the new system.

"This specific system, players didn't play so much that system and then you need always to learn from that system and this needs time," he said. "We are still learning things from that system."

Tadić also gave an insight into Puel's thoughts after the game.

"That we should have more courage to play and to do things together – to attack together, to defend together, and we try to follow him and to listen to him," he said.

"We want to improve every day, to give our best and that's it. We just want to see what is good and what is not good on this game, and try now to win the game against Sunderland. This is most important. It's important to win some games, then you get extra confidence and for the rest of the season you can do better things."
