The 20-year-old centre-back, who has represented England at under-18s, 19s and 20s level, is seen as a star of the future, and with new boss Mauricio Pochettino keen to develop young English talents, he has been highlighted as a priority in the club's list of summer targets.
But does he have what it takes to make the step up to the Premier League?
Last season Lascelles starred at central-defence for Forest, winning three man-of-the-match awards, as his side achieved an 11-place finish. He has become a first team regular for the Championship club, with his displays attracting interest from a number of premier division clubs.
The 6'2" defender is highly regarded in the world of English football, and rightly so. He is terrific in the air and strong in the tackle, whilst he displays a maturity beyond his years. He shows an intelligence when breaking down opposition moves and he is more than happy to carry, or pass, the ball out of defence.

Courtesy of WhoScored, we can provide Lascelles statistics from the previous campaign. He registered at least one tackle and interception per match, alongside 9.1 clearances. Meanwhile, he completed three of every four attempts to find a team-mate. His ability to read the game highlights his intelligence, which is staggering for such a young footballer.
He has grown accustomed to the physical nature of the British game during his time spent in the second division, and in this regard, he is well prepared for the step-up to top-flight action. When it comes to learning the ropes in England, there is no better school than the Sky Bet Championship.
Laurie Whitwell of the Daily Mail has previously compared the youngster to the likes of Vincent Kompany and Rio Ferdinand; high praise indeed. She has also expressed similarities to current Spurs captain Michael Dawson, who also graduated through the Forest youth academy.
Lascelles is touted as a future England star, and based on this notion, it's almost certain that he'll end up in the Premier League within the next few seasons. But at just 20, another year or so spent in the Championship would be ideal for his development.
Nonetheless, if Spurs approach Forest with a suitable offer, the club could find it hard to turn it down.
