Radamel Falcao: Seven players that suggest Manchester United might have made a massive mistake

Manchester United announced last night that they would not be signing Radamel Falcao on a permanent basis.

The decision came as little surprise; The Colombian scored just four goals during his season long-loan from Monaco and with a fee set at £43.2m, United decided it was simply too much - particularly for a 29-year-old with little re-sale value.

But could they live to regret the decision?

Prior to his arrival at Old Trafford, Falcao was considered among the most deadly strikers on the planet. Excellent records at Porto, Atletico Madrid and Monaco indicated United had pulled off a coup in bringing him to Old Trafford. Only it didn't work out.

If Falcao re-finds his form, he wouldn't be the first player Manchester United regret letting slip from their grasp. We take a look at some others who flourished after waving goodbye...

Will Manchester United regret letting Falcao leave? Let us know in the comments below.
