Antony has been putting in extra work during the international break that will leave Manchester United supporters and manager Erik ten Hag delighted.
The Brazilian has endured a difficult second season at Old Trafford that has been marred by poor performances and frustration from fans over the huge transfer fee paid by United.
Antony arrived in Manchester two-years-ago following his £85.5million move from Ajax and has scored just 10 goals for the club, with just his second of the season coming in United's recent FA Cup win over Liverpool.
However, the passionate forward appears determined to turn his form around and has been working hard at a specialist training facility during the international break.
Antony failed to make the cut for Brazil's latest squad in friendlies against England and Spain, but rather than relaxing at home whisked himself away to Madeira for a personal training plan.
The Fisio Clinic has several locations across Europe with a focus on rehabilitation, physiotherapy and helping athletes reach the peak level of physical performance.
Posting an update on their Instagram account, Antony was seen being put through a series of strength and conditioning exercises in the clinic's private gym ahead of the Premier League resuming this weekend.
'It is with great pleasure that we welcome the renowned international athlete Antony Santos to our Performance Medical Gym!' the clinic captioned their post.
'At our space, we are constantly seeking to raise the standards of training, helping athletes reach new heights of performance. The presence of a player as talented as Antony Santos only strengthens our commitment to excellence.
'Thank you for choosing our clinic for your training. It was an honour to have you with us!' they added.
Antony has largely been cut out of United's starting team this season by the impressive performances of Alejandro Garnacho as the club's mainstay right-winger.
His recent vital goal against Liverpool to force extra time in the FA Cup clash could be viewed as a turning point in his disappointing career so far in England.
Speaking after his goal, Antony said: 'It has been a period of a lot of learning. I try to learn from each criticism, understand where I can improve.
'I have been working silently to evolve and show my football on the field. I have also been training my right foot, to make it better.
'I know my potential and I know why Manchester United hired me. I want to repay all of this on the field.'
