Middlesbrough boss Neil Warnock says he is relaxed about his players who are soon to be out of contract, including striker Britt Assombalonga.
Assombalonga cost a club record £15m from Forest in July 2017, and since scored 47 goals in 152 games.
"We don't worry about that [the contract] here," said Warnock.
"There are a lot of players out of contract. What will be, will be, we'll worry about that when we have to."
The DR Congo international has consistently managed double-figure seasons in the English Football League since being handed his chance to impress at Southend, following that record at Peterborough, Forest and Boro.
