Gary Neville firmly believes that Cristiano Ronaldo’s return to Manchester United has brought them into the title conversation, but thinks that Manchester City and Chelsea remain the favourites for Premier League glory this season.The Red Devils confirmed on Friday afternoon that they had agreed a fee with Juventus for a sensational return to Old Trafford for the Portuguese legend. However, that is still subject to the 36-year-old agreeing personal terms and completing a medical.Although Neville thinks the five-time Ballon dOr winner guarantees goals and will raise standards at United, he does not feel Ronaldos impact can lead them to the title though they have a much better chance with him in the side.“I made the prediction that it would be Manchester City, Chelsea and Manchester United [in that order] and Im not going to change that because of the signing of Ronaldo,” Neville told Sky Sports following Chelseas 1-1- draw with Liverpool.“Im going to stick with that because I dont think the Ronaldo signing makes them a better team than Chelsea, who were the Champions League winners last season, or Manchester City, who were 20 points clear.“Absolutely it brings them closer to winning the title, it will absolutely get them closer. But do I think it will win them the title at this point? No I dont. But now Im more excited about Manchester United challenging for the title than I was maybe five or six days ago.“I dont think they will. I want them to. Cristiano Ronaldo and Raphael Varane will have the mentality to win United the title, theres no doubt, but if I had to put my house on it now, do I think theyll win the title this season? No. But Im desperate for them to win the title. Im just being pragmatic.“I think theres an element that you have to be in for these players if youre Manchester United. Whether that wins you the title or not, Im unsure. It gives them a far better chance than they had 48 hours ago.How will Ronaldos return impact Man Utd? “He isnt coming for Champions League places. Hes coming for personal accolades and titles. There is no doubt about that. I hope that he can be the difference, because if he gets 10% out of every other player theres a big chance. Theres a big chance.“But lets be clear, Manchester City have been exceptional for the last three or four seasons. Chelsea just won the Champions League and now have a better team this season. So theyre also against the best two teams in Europe, three if you count Liverpool.“The Premier League is at the highest standard it has been for a long, long time. Its not an easy Premier League this one, its got back to the top level in Europe and I think Manchester United are up against really good sides.“In years gone by I might have said this Man United team will win the title by 10 points, but its such a strong Premier League this one.”READ MORE: Cristiano Ronaldo only half the player, as pundit criticises Man Utd return
