Radamel Falcao's initial loan spell with Manchester United can be terminated by the Premier League club in the event that he suffers a repeat of the serious knee injury that forced him to miss this summer's World Cup.
Colombian striker Falcao - who joined the Red Devils from Monaco for the rest of the 2014/15 season on transfer deadline day and is likely to make the move permanent next year - missed the tournament in Brazil and the latter half of his one and only campaign in France after suffering anterior cruciate ligament damage during a routine cup win over Chasselay Monts d'or Azergues in January.
Having undergone surgery and a stringent rehabilitation programme, the 29-year-old appears fully fit - if somewhat lacking in match practice - once again. However, if such a problem were to return, then reports cited by The Independent claim that Manchester United have the option to cut his spell at Old Trafford short and send him back to the Stade Louis II.
Manchester United supporters - many of whom were shocked that much-maligned executive vice-chairman Ed Woodward and co were able to successfully negotiate a switch for such an in-demand star - will be praying that does not happen, of course, with Falcao sure to become an integral figure of their attack under Louis van Gaal.
Having made his Premier League bow for the club as a second-half substitute during last week's 4-0 humbling of newly-promoted Queens Park Rangers. the world-class forward - who reportedly earns just shy of £300,000-per-week at Manchester United - was handed a starting berth for today's trip to Leicester City in a formidable lineup that also included Angel di Maria, captain Wayne Rooney and Robin van Persie.
Unfortunately for Falcao, however, he could not cap his full debut with a goal and left the field with just under 20 minutes to play at the King Power Stadium as Nigel Pearson's side demonstrated remarkable character to fight back from a two-goal deficit - with a little help from referee Mark Clattenburg - to secure a thrilling 5-3 victory.
