Britoli Curtis Assombalonga was born on December 6, 1992, in Kinshasha, Zaire. His father, Fedor, migrated with his family to London, when Britt was just eight months old.
Having successfully come through the Hertswood Academy, he signed for the Watford Youth team at the age of 17. His consistent growth and performances earned him a one year contract at the end of the season.
Due to his lack of opportunity in the first team, he was sent out on loan on November 2011 to National League side Wealdstone FC, where he became an instant hit, and at the end of his three-month loan spell at the club, he had scored 11 times in 16 games.
On his return to Watford in February 2012, he was rewarded with another one-year contract extension and a loan move to another National League side Braintree Town. Again, it was prolific stint as he netted 5 goals in 5 games, which earned him a recall back to the senior squad.
At the beginning of the 2012/2013 season, he took up another loan challenge, this time at a league two side Southend United, and he produced 15 league goals in 43 appearances, making him the club’s top marksman and the joint seventh highest goal scorer in the league.
Unfortunately, his team missed out on their single chance of silverware that season as they lost 2-0 to Crewe Alexandra in the 2013 League Trophy final.
When Peterborough United, a league one outfit, came knocking in the summer of 2013, Watford sold him in a deal worth over £1 million, breaking Peterborough's transfer record.
It took him little time to become the fans favourite as his eight goals in his first ten games resulted in the fans composing the “Let’s do the Conga for Britt Assombalonga” chant. At the end of the season, he finished with 23 league goals, just one behind the league’s top scorer Sam Baldock of Bristol City.
He won his first career silverware and scored in Peterborough's 3-1 victory over Chesterfield in the 2014 Football League Trophy final. At this point, Assombalonga’s prospect of moving on to a bigger club in the summer grew rather conspicuous. The forward moved a level up to Championship club, Nottingham Forest, on a five-year contract worth £5 million, another club-record transfer fee.
In his three year stay at the club, he managed to score 30 league goals in 65 appearances, averaging at almost a goal in every two games in a league as competitive as the English Championship. In the summer of 2017, newly relegated Middlesbrough FC approached Nottingham Forest and successfully secured the signature of the Congolese born forward on a four-year contract worth £15 million.
