Wenger said Pogba did very well against Atalanta, adding that the France international gave the visitors more power when he came off the bench in the second half during the encounter.
According to him, Fernandes, who had a poor first half, played well in the second half of the match.
Man United came from 2-0 down to beat the Serie A side at Old Trafford, thanks to three goals from Marcus Rashford, Harry Maguire and Cristiano Ronaldo.
Pogba entered the fray for McTominay in the 66th minute with United trailing 2-1 and Wenger was impressed by what he saw in the midfield trio of Fred, Bruno Fernandes and the France international.
Speaking as a pundit on beIN SPORTS, Wenger said: “Pogba, I thought, did well. Pogba gave them more power out from deep in midfield by creating more dangerous balls.
“And when Pogba came on, Fernandes became better. Fernandes had a poor first half, but in the second half, he came alive as well.”
Man United’s next match is against Liverpool in the Premier League this weekend.
