Tevez has made a stunning impact since his return as he helped assist the deciding goal on his first appearance this year against Chelsea. He also scored a hat-trick against Norwich on Saturday and with goals drying up for City earlier in the year, many observers have commented that Tevez's presence could have helped City preserve their lead over Manchester United and put them on track to win their first league title since 1968.
Milner believes that such talk is divisive and does not help the squad's morale and so he commented that City should focus on the present instead of dwelling on the past.
"It's pointless going there really because that's been and gone," Milner told Sky Sports.
"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."
The England midfielder refused to be drawn in on questions focusing on City's chances in the title race and he insisted that all he wants his team to do is to focus on securing maximum points in their four remaining fixtures. And he is optimistic that his club will do better in the next season.
"We'll just keep doing what we've done all year and concentrate on our business," he 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.
"The belief is there from the players and the fans.
"We expect to win every game and so do they - and we know we can beat any side on our day but it's about going out there and playing well on a consistent basis."
Manchester City next play Wolves on Sunday and will then have to prepare themselves for the Manchester derby the following week. United can clinch the title at the Etihad Stadium if they manage to win the derby on April 30.
