See it also about rotation what people are missing, Hazard, Mata and say Oscar wont play every game and will need to be rested and or covered for injuries etc. Rooney can play up top or deeper like already said, Ba should be moved on because with three of Lukaku, Torres and Rooney that's enough. You have to take into consideration players will tire and this is the problem last season, we could never look to the bench and replace quality with quality, it was Yossi or Marin sat there. So the scenario is Mata is allowed to start a game from the bench due to tiredness Rooney could fill the gap allowing Lukaku to lead the line and Torres as back up. As bad as Torres has been I certainly wouldn't mind looking to him from the bench to come on and nab a goal, perfectly fine. Jose can and will integrate them all if we sign Rooney, and if anyone can keep these players happy it's Jose. City have a plethora of top attackers, and it's needed, what's important is keeping them happy and utilizing them to their strengths to benefit the team thus allowing others not to burn out. It's a long season.
