It would be hard for most Manchester United fans to admit that they covet their neighbours' possessions.
But prejudice aside, these five world class footballers would surely be welcome if they decided to move to Manchester, or for some, swap their blue shirts for red.
Here are my top five, and if you disagree, make sure to sound off on who you think should make the list below.
There are few better box-to-box midfielders than Manchester City's Yaya Toure.
Powerful, quick and technically accomplished, since making a £24 million move from Barcelona in 2010, the Ivorian has quickly become one of, if not City's most important player.
Besides the fact that he just happens to play in the position that the Red Devils are in most need of, a player of his ability would always be welcome at United.
It's just a shame for fans that he plays for their biggest rivals.
This pick should really have an asterisk beside it, or at least read "A Healthy Jack Wilshere."
But his ability and potential are unquestionable.
And if he is to stay healthy over the course of the next few years, Wilshere will most likely develop into England's premier central midfielder, and the nation's closest weapon to matching the technique and guile that so many of Spain and Italy's players possess.
What Sir Alex would give to have had the English playmaker develop and prosper in United's youth teams.
As it is, he will have to "make do" with Tom Cleverley, a more than capable alternative.
The genius of Gareth Bale is well acknowledged by those who follow the Premier League.
And whilst United aren't exactly short of wingers, Ashley Young on the left flank has not yet proven he can be as reliable as Ryan Giggs was in his day.
Bale, on the other hand, is a player capable of winning a game with a single moment of genius.
Last season he also showed how he can also contribute when playing in a more central role, scoring a few headers in the box and goals from one-on-one opportunities.
Why wouldn't Sir Alex want to replace one Welshman with another when Giggs retires?
Another attacking midfielder of such extraordinary quality, United fans would be in serious denial if they claimed that this man wouldn't walk straight into the team's starting XI if he moved today.
Sir Alex even came close to signing David Silva in 2010, when his former club Valencia was looking to sell.
Indeed, with Yaya Toure and Silva both moving to City that year, it could be said that United missed out on two world class players who have since played a huge part in bringing the blue half of Manchester its first league trophy in over 40 years.
Just another reason to cast an envious eye over United's biggest rivals.
Before I begin extolling the virtues of Luka Modric, let me start by saying that I believe Tottenham's £40 million valuation is too high.
It is a great price to pay for a player who is soon to turn 27 years of age, no matter how talented he is.
But boy is he talented.
On paper, he is very close to being exactly the kind of player United currently need right now—he can move throughout the centre of midfield, dictating its pace and flow with ease.
Real Madrid will be picking up a heck of a player if they sign him this summer as expected, but will surely pay a hefty price for the privilege.
