Manchester United has basically used a 4-4-1-1 template in the last season or so, with Wayne Rooney constantly dropping in between the midfield and attack to create for his team.
Though Rooney has done well in that role, it may be more beneficial for the team if he were to spend more time closer to goal.
If Sneijder joined Manchester United, the team could line up in a variety of ways.
Here is one possible starting 11 to include Wesley Sneijder.
David De Gea has given Manchester United fans more than a few reasons to doubt him, but he has coupled that with some reasons to like him too.
With one full year under his belt in the Premiership, he will only get better.
Manchester United has a solid young right-back in the form of Rafael. When he is fully fit, he is a sure starter for this position.
Phil Jones was a great buy for the club over the summer. He has shown great talent and versatility during the season and is more than capable of grabbing the starting spot with Rio Ferdinand on his last legs.
Nemanja Vidic is the club's rock in defense, and the team has missed its captain at times this season.
Patrice Evra is still one of the world's best left-backs, and this selection is obvious.
Michael Carrick does his job game after game without fuss.
Wesley Sneijder is a fantastic creator and can bang in his share of goals as well. He would be the main creator in this formation.
Tom Clevereley alongside Wesley Sneijder? I think so. I said last week that Cleverley could do with more time behind Sneijder, but after more thought on the matter, he should just play beside him.
People continue to praise the youngster, and his play this season is certainly deserving of a continued starting role.
If you haven't realized by now, yes, the formation would be 4-3-3.
Injuries sometimes get in the way of prolonged runs for the Ecuadorian, but Antonio Valencia is arguably the club's best out-and-out winger.
Nani has grown since Cristiano Ronaldo's departure. There may still be another level for the Portuguese winger to reach, and it would be interesting to see him in a 4-3-3 formation.
Wayne Rooney has all the tools to lead the team as the lone forward and him linking up with a duo of both Wesley Sneijder and Tom Cleverley would be nice to watch.
Sir Alex Ferguson has shown different formations at various times in his career, but 4-4-2 has been a key part of the manager's arsenal.
With a player like Wesley Sneijder in the mix, 4-3-3 may be the best bet, especially if Tom Cleverley is to play as well.
Manchester United would still have its great depth in all positions and could revert to its regular 4-4-2, or even a 4-2-3-1 with Carrick and Darren Fletcher behind Sneijder.
Fans may point out the omission of Javier Hernandez or Danny Welbeck, but they would still get a great amount of games in the team's usually long season.
Hernandez would be the main option behind Rooney and provide something different in the process. Welbeck would still be used in his preferred position up front, but could be another choice on the wings besides Ashley Young.
In midfield, Fletcher and Anderson could fit in alongside either playmaker, and Fletcher especially could fit in as the defensive midfielder if really necessary.
Phil Jones could do that job as well, and as a result, Ferdinand or Chris Smalling would step in to his position in defense.
