Sir Alex Ferguson was unable to find the regular role in Manchester United's side that the Argentine was after during his two-year spell at Old Trafford after arriving from West Ham, and so, astonishingly at the time, Tevez was sold to rivals Manchester City in the summer of 2009.
He shared the Premier League Golden Boot with Dimitar Berbatov in his first season with the Citizens, and fired them into the Champions League for the first time the season after. With the arrival of Sergio Aguero he played a lesser role as City won the title in 2012, before rediscovering some form and departing for Juventus in 2013.
Since arriving in Turin Tevez has proved he has plenty to offer despite approaching the latter years of his career, and he boasts 45 goals in 83 games.
Given Falcao's astonishing goalscoring record everywhere else he has played, United would be running a major risk not to reconsider any decision to pass on his signing.
The Colombian, who has been linked with Juve this season, has outscored the likes of Tevez throughout his career, and it would be foolish to think he is a spent force as a top class striker.
With Rooney himself now approaching his 30s, and Robin van Persie struggling for fitness, the reason Falcao was brought to the club, the need for a world class centre forward, is just as relevant as it was last summer.
United would de devastated if they decided not to pursue the Monaco forward, only for Falcao to sign and return to form at another European giant like Juventus, or even worse, at a Premier League rival.
Unless a world class centre forward transfer option appears, who is significantly younger than the current attacking Louis van Gaal has on offer, snubbing Falcao could prove to be a costly move.
