After a frustrating final season at West Ham, new Tottenham signing Mohammed Kudus is looking to rediscover the glittering form that made him one of European football's hottest properties just two summers ago.
The Ghanaian completed his £55m move to the Tottenham Hotspur Stadium on a long-term contract on Thursday.
BBC Sport looks at why new boss Thomas Frank wanted to add him to his squad â and why the transfer is a rare move for the north London outfit.
Kudus was the subject of huge interest from Premier League clubs in summer 2023 after a string of eye-catching displays in Ajax's 2022-23 Champions League campaign.
The Dutch giants were eliminated at the group stage but Kudus set up six goals in as many appearances - including a stunning effort off the underside of the bar in a 2-1 defeat against Liverpool at Anfield - catching the eye of Chelsea, Arsenal and Brighton, among others.
It was West Ham, though, who won the race to sign the Ghanaian, who wasted little time in recapturing the form of his final year in the Netherlands, plundering eight goals and six assists in the league in an excellent debut season under David Moyes.
Named the Premier League's best newcomer by Sky Sports pundit Gary Neville at the end of the campaign, Kudus also won West Ham's goal of the season award for his magnificent solo effort against German club Freiburg in the Europa League.
His second season with the Hammers, however, was underwhelming to say the least.
Kudus struggled to adapt to Graham Potter's wing-back system after the Englishman succeeded Julen Lopetegui in January 2024, his final-day effort against already-relegated Ipswich Town one of only two efforts under the former Brighton boss.
He was often deployed as a striker by Potter and only rarely featured wide on the right, arguably his best position but one in which West Ham already have skipper Jarrod Bowen.
The Ghanaian attempted the most dribbles in the Premier League for the second season running in 24-25 - 198 compared to 281 the season before - but his success rate dropped from 55.9% to 47%.
He was also much less effective off the ball last term, winning back possession on 148 occasions compared to 298 times in his debut campaign.
Perhaps his most telling contribution - if you can call it that - in his final year with the Hammers came in a 4-1 defeat against Spurs last October, when he was sent off for kicking out at defender Micky van de Ven and raising his hands to both the Dutchman and midfielder Pape Sarr.
Kudus, who was subsequently handed a five-match ban, later said he was "deeply embarrassed" by his actions.
"Kudus can add attacking threat to Spurs either from the right flank, cutting inside, or from a more central position," explains former West Ham assistant Edu Rubio.
"He is very versatile and like Bryan Mbuemo - who became a very effective and important player for Thomas Frank at Brentford - can add goals, pace and work-rate when pressing high.
"Kudus can add an aggressive high-press style, since his approach to closing down the man on the ball is exceptional. He is rapid, intense and effective with it. He can add goals into the squad, too.
"He can be a game changer. He just needs to find that consistency needed at the top. He fits Thomas' 4-3-3 and 3-5-2 and also the manager's desire to have quick and direct attacks when possible; therefore I believe Kudus can reach his potential and the consistency under a manager like Frank.
"He may need to improve his variation on decision-making when on the ball, especially when playing centrally as he tends to get more exposed there and lose more possession easily.
"Overall he can add goals, work-rate off the ball, uniqueness and pour desire and character into the squad. He is a very exciting player."
Daniel Levy has often been criticised by Tottenham fans for a perceived lack of investment in the playing squad, but when the chairman does do business it is rarely with the club's London rivals.
Kudus is the first player to move between West Ham and Tottenham since August 2011, when Scott Parker signed for Spurs following the Hammers' relegation from the Premier League.
You have to go back even further for the last transfer between Spurs and Chelsea, who have not struck any deals since goalkeeper Carlo Cudicini moved from Stamford Bridge to White Hart Lane in January 2009.
Former France international defender William Gallas was the last player to move across north London from Spurs' fierce rivals Arsenal, joining on a free transfer in August 2010.
The only other West Ham player to join Spurs in the past 20 years was back-up goalkeeper Jimmy Walker, who failed to make a first-team appearance under then-manager Harry Redknapp after signing in 2009.
Former England internationals Michael Carrick and Jermaine Defoe both moved from Upton Park to White Hart Lane in 2004, while striker Frederic Kanoute joined Tottenham from the Hammers in 2003.
