The 29-year-old Colombia international striker, who joined the club on loan from Monaco in September last year, has made just 28 appearances, 12 of them from the bench, and scored four goals, and all the indications are that United boss Louis van Gaal will not exercise an option to complete a permanent deal.
Now Falcao's mother Carmenza Zarate has admitted it has been a difficult time for her son and hinted his future could lie away from Old Trafford as he looks to resurrect his career.
She told Colombian newspaper El Espectador: "Not everything has been easy in Falcao's life
He has had some difficult moments in his career.
"They slowed his progress and prevented him from participating in important competitions like the World Cup, or have confined him to the bench, like in Manchester.
"I often remind him that after a test or a difficulty, blessings arrive
We hope for bigger and better things
God hasn't abandoned us and my son will become again what he has been, a goalscorer.
"Even if he's unhappy not to be in the starting XI, he has to accept the coach's decisions
It's not a normal situation given what he has experienced in his career, but it happens in football.
"If God shows him a new path, he'll leave Manchester; if not, he'll stay."
Despite her son's problems, Zarate refused to blame Van Gaal and his management style, insisting his treatment of other big-name players suggests he has nothing against the South American.
She said: "I believe what he (Van Gaal) does with Falcao is not personal because the same thing happens with Angel Di Maria and Robin Van Persie
It's his way of working, and you have to respect that.
"He (Falcao) has to prove results for the Manchester United executives, and we will see how he achieves that."
Falcao made his debut for United as a substitute in a 4-0 league victory over QPR on September 14 and started for the first time in the 5-3 defeat at Leicester a week later, opening his goalscoring account in a 2-1 win against Everton on October 5.
