The mercurial midfielder gave away a penalty in United's 6-2 win over Roma in the Europa League semi-final first leg on Thursday.
Despite scoring in the match, Pogba acknowledged he needs to work on his tackling.
On the penalty decision against him, he said: "Just don't tackle.
"I don't know how to tackle. I try to be the English guy. I need to practise more. I need to practise to tackle without arms. It's unlucky. I've been unlucky a lot this season with penalties."
United hold a huge advantage heading into the second leg, but Pogba warned the tie was not over.
"The result is positive but it's not finished," he said. "We will have to say focused and play a nice game with the same mentality.
"In the first half we had two mistakes and conceded two goals. We were a bit all over the place after the second goal.
"At half-time we said let's do the right things, let's do simple things. The manager spoke. We were all motivated to score as many goals as possible."
