The bitter city rivals will battle it out for the Polish strikers signature.
Manchester City are set to fight it out with bitter rivals Manchester United over the signing of Borussia Dortmund striker Robert Lewandowski, the Sun reports.
Both clubs appear to be ready to bid £25.5 million for the Polish striker, although City appear to me more interested at the moment.
City have been in contact with the players representatives to register their interest and are ready to make the striker one of the highest paid players at the club.
However, the club have been told that the striker still has his heart set on a move to Bayern Munich.
It was thought that Lewandowski would make the move to Bayern this summer but Dortmund recently stated that the club would not let the Polish striker leave for their rivals and that he would have to see out the remainder of his contract which expires next year.
This has thrown the race for the striker wide open, with Real Madrid also said to be interested and both City and Madrid are likely to offer better wages than Bayern.
It remains to be seen whether the Polish striker will move this summer or wait until next summer and make what he calls his dream move to Bayern Munich.
