The midfielder player is back in Yorkshire with Leeds United after a spell across the Pennines.
Posting on Thursday, Hughes claimed it was "a tough decision" to leave Manchester United, but added that he was "excited for the new challenge" at Leeds.
The move sees the Teessider return to Yorkshire, where he played for Middlesbrough's academy until the Red Devils came calling in early 2018.
Hughes is part of an influx of young arrivals at Leeds this summer.
Fellow shoolboys, Stuart McKinstry and Morten Spencer have also moved to Elland Road from Motherwell and Sunderland, respectively.
Spencer, who is another Teesside native, was among those who replied to Hughes' Instagram post, writing: 'Love it brother".
Leeds have also brought in Liam McCarron from Carlisle United, as well as Rafa Mujica and Guille Amor from Barcelona this week.
However, the trio are expected to begin their Whites careers above Hughes and company in Carlos Corberan's Under-23s.
