The Argentine has come back to score four in his last two starts but the former Leeds man is unsure if his side would have been in a better position with him in the side all season
Tevez missed six months of the season after publicly falling out with City boss Roberto Mancini and, despite enjoying success throughout much of the Argentine's absence, the side now trail Manchester United by five points with time running out in the Premeir League title race.
But the former Aston Villa midfielder was keen not to dwell on what might have been and hopes that Tevez can maintain his form for the rest of the campaign.
Milner, who was speaking at the launch of his foundation that will raise money for several charities, said: "It's pointless going there really because that's been and gone.
"Carlos is playing for Manchester City and playing well. He got a great hat-trick and Sergio [Aguero] was fantastic.
"There were a number of great performances at the weekend so it's pointless thinking about what might have been.
"We're lucky to have a player like Carlos Tevez playing the way he is and hopefully we get a few more hat-tricks out of him between now and the end of the season."
Despite being five points behind rivals Manchester United, the England international insists his side have not given up on the Premier League title this season.
"We'll just keep doing what we've done all year and concentrate on our business," Milner said.
"We've got tough games left and we'll try and win the rest of those and see where that takes us.
"Manchester United are obviously a top side. They've got that experience of winning trophies and been there year upon year.
"We've performed well; we've had a great result at the weekend.
"All we can do is concentrate on our business and if that's good enough then great, and if not we'll learn from our mistakes that we've made this year and try and go again next year.
