Much has been said about the fitness of Robin van Persie and whether he should be starting every match for Manchester United given his current form.
If Louis van Gaal were to drop him from the team for Sunday, a 4-5-1 formation could be used with Radamel Falcao as the lone striker up front.
Many feel Van Persie and Falcao almost get in each other’s way up front and without the Dutchman there, Falcao could have a free reign of the space up front.
Michael Carrick in a deep anchor role would allow Blind to play further up in midfield and up against a physical Chelsea side, it would be the biggest midfield trio United could utilise.
Could a 4-5-1 formation be the perfect way for Falcao to spread his wings and really find his feet at United?
