Radamel Falcao thanked Manchester United fans on Twitter earlier today, in what could be the Colombian's last goodbye to Old Trafford.
'Thank you so much for the incredible support of the @ManUtd fans all season. Unforgettable,' he tweeted to his 8.5 million followers. The post was accompanied by a photo of the United players applauding their audience in a lap of honour at Old Trafford.
The striker scored 72 goals in 87 appearances for Porto, 70 in 91 for Atletico Madrid and 13 in 22 for AS Monaco, but has failed to show the same prolific goalscoring ability since being brought in by Louis van Gaal at the start of the season.
He has netted just four times in 14 league appearances for United, and has been a huge disappointment given his billing as one of the deadliest strikers in world football.
Despite starting against Arsenal at the weekend, Falcao was subbed off after an hour. He waved to the fans as he walked off the pitch. And today's tweet looks to have confirmed that United will not make the Colombian's move permanent, at the cost of £46 million.
The 29-year-old missed the 2014 World Cup due to a recurring knee injury which may have affected ability. But teammate Chris Smalling is convinced Falcao will come good, he said to the Daily Star: "He's had a couple of injuries along the way, and that means you don't get the consistency of being able to train every week.
"I think when the manager his given him the chance and he's trained well and stayed fit, you can see he is getting sharper and with a good pre-season he'll be firing again next season."
It does not look likely though that United will take a £46m risk on a striker who, through no fault of his own, may be past his best.
