The 18-year-old is still in the early stages of his Sunderland career after completing a move from his boyhood club, Birmingham City, in the summer.
Bellingham came through the academy ranks at Birmingham, before going on to make 26 competitive appearances for the first-team.
Since joining Sunderland, the teenager has established himself as a key part of the side, starting 20 of the club's 22 league matches.
The midfielder, who has predominantly been used in an advanced role, has scored four Championship goals this season, including the winner in a 1-0 victory over Leeds United in Sunderland's most recent home game on December 12.
While he may have only been with Sunderland for six months, Bellingham is already attracting interest from a number of top Premier League clubs.
According to journalist Ekrem Konur, Liverpool, Chelsea and Arsenal sent scouts to watch Bellingham in Sunderland's away clash with Bristol City on Saturday.
Unfortunately, they had to wait until the second half to see him in action after he was left on the bench for the fixture at Ashton Gate.
With Sunderland 1-0 down, interim boss Mike Dodds turned to Bellingham just after the hour mark, bringing him on to replace Abdoullah Ba.
Bellingham, who picked up a yellow card within five minutes of his arrival, was unable to spark a fightback against the Robins, as his side fell to a narrow defeat.
While Bellingham may have been watched by three of the Premier League's biggest clubs, they are not the only teams monitoring his development.
A recent report claimed that Tottenham Hotspur are showing an interest, having regular sent scouts to keep up to date on his progress.
Spanish giants Real Madrid are also believed to be keeping tabs on the youngster's performances, as they weigh up a potential move that could see him play alongside his brother, Jude Bellingham.
The 20-year-old has already made a significant impression at the Santiago Bernabeu following his summer arrival from Borussia Dortmund.
The England international has top scored for Real Madrid this season, netting 16 goals in 19 appearances across all competitions.
