The highly-rated academy graduate has already featured twice in Sam Allardyce’s first-team, and his breakthrough into the senior squad has been rewarded with a three-year deal at the Boleyn Ground.
The 18-year-old, who joined the Hammers aged nine, made his debut back in January during an FA Cup tie with Nottingham Forest whilst still a first-year scholar.
His bow coincided with a run in Neil Dewsnip’s U18 side last season, winning the first of his five caps last October as the Young Lions thumped Hungary 4-0. His last appearance came in April as he helped his country to a 2-1 win over Germany.
Burke has continued his progress since, and he enjoyed an impressive pre-season, which included trips to New Zealand and Germany with the first-team, and a first goal in the 3-2 victory over Sampdoria.
His first competitive start for the seniors then followed as Allardyce picked him for the visit of Sheffield United in the League Cup first round.
“It's a great achievement for me,” Burke told West Ham TV. “My first professional contract for the club and to sign for a great club like this is really good.
“I started off pre-season away with the first team and obviously did quite well there, came back, scored my debut goal and have just carried on from there. I'm doing well, and I'm just glad it's come to this.”
