Find out which of the two rivals’ stars on show at the World Cup would make the Manchester starting XI.
GK – Joe Hart (ENG)
RB – Pablo Zabaleta (ARG)
The Argentina full-back has had another impressive campaign with Manchester City and is one of the Citizens' best players. Rafael has not been called up for host nation Brazil, so this was a no-brainer.
CB – Vincent Kompany (BEL)
The City skipper is undoubtedly one of the best central defenders in the world and he will be looking to prove that with Belgium this summer.
CB – Phil Jones (ENG)
The young England international has suffered a number of injuries this term and is still working on recovering at present, but I think that he is a better defender than Argentina’s Martin Demichelis, who made a number of errors this term with City. If both were fit, I’d be giving the United youngster the nod.
LB – Patrice Evra (FRA)
Gael Clichy has been overlooked by France, who have favoured United’s vice-captain Evra. If he is good enough for France, he is good enough for me.
CM – Fernandinho (BRA)
The City box-to-box man will be on display with Brazil this summer and I definitely think that he deserves his place in the team more than United’s signing last summer, Marouane Fellaini, who will be in attendance with Belgium after a disappointing debut season at Old Trafford.
CM – Yaya Toure (IVO)
The Ivory Coast midfielder deservedly makes the team – his contribution to City’s Premier League title win was nothing short of sensational this term and he will likely be dazzling for his country too.
AM – David Silva (SPA)
In terms of a playmaker, two of Spain’s finest in City’s David Silva and United’s club-record signing Juan Mata give me a cumbersome dilemma but, in terms of performance this season, the Citizens’ maestro edges it over his compatriot, who didn’t get many games at Chelsea and still needs to settle at Old Trafford.
FW – Wayne Rooney (ENG)
I’m playing a 4-3-3 because Manchester just has too many superb attacking players, but the team would not be complete without United’s best player by a country mile this term: the England No.10 Wayne Rooney.
FW – Edin Dzeko (BOS)
Having picked Rooney, I’m leaving out Robin van Persie in favour of the Bosnian international, who had his best season at the Etihad Stadium this term. Netherlands striker Van Persie had suffered injuries and was nowhere near his form from his first season with the Red Devils, so Dzeko gets the call.
FW – Sergio Aguero (ARG)
Finally, this was the easiest choice of all. No Manchester XI would be complete without City’s Argentine talisman, who set the Premier League on fire once again this term for the champions.
