Opinion: One-season wonder to club legend; Harry Kane’s evolution at Tottenham

Once upon a time, rather naively by rival fans, Harry Kane was dubbed a one-season wonder. However, some seven years and roughly 160 additional Premier League goals later (PL.com), that could hardly be further from the truth.
Since becoming a starter for Tottenham back in 2014/15, Kane has been the epitome of consistency, reaching 20+ goals in five of his eight seasons and never ending a campaign with fewer than 15 goals (TransferMarkt).
Remarkably, whilst maintaining this impressive output, his game has unquestionably evolved, as a now 28-year-old Kane is unrecognisable to the young starlet who first graced White Hart Lane.
Starting as a pure out-and-out striker, Kane has arguably become the most complete forward in the Premier League, if not world football, boasting a repertoire of skills coveted by any player.
But how has he reached this point"
In his first three full Premier League seasons, the Englishman bagged 21, 25, and 29 goals; two of his three best goal-scoring years (TransferMarkt).
30 league goals in 2017/18 saw Kane finish with his best tally to date, perhaps reaching the peak of his pure forward iteration (TransferMarkt).
Kane?s 5.21 and 2.11 shots and shots on target per 90 saw him rank in the top one and three per cent of forwards in Europe?s top five leagues for these respective metrics (FB Ref), marking his highest shot volume across any of the last five seasons and perfectly defining his role in the side.
Simply put, Kane was there to take shots and score goals, and he did so expertly. Operating predominantly in front of Son, Eriksen, and Alli, Kane also received his highest number of progressive passes across the last five seasons ? 9.28 per 90, however interestingly recorded just 0.29 goal-creating actions per 90.
Whilst comparatively low against other seasons, this figure is telling in reinforcing Kane?s role in the side and serves as a notable benchmark when reflecting on his transition.
That season, the vast majority of Kane?s goal-creating came via shots, and moreover converting chances, differing immensely to now where he plays a more active and complete role.
By his own standards, 2018/19 and 2019/20 may be looked back on as somewhat underwhelming seasons for the Englishman, however in 2020/21, he returned as a different beast.
Under Jose Mourinho, not necessarily by choice, Kane was forced to collect the ball from deeper positions which whilst sometimes frustrating, has certainly helped facilitate his development as a playmaking forward.
His overall involvement in games was heightened, and as a bi-product, had more touches, and both attempted and completed passes across the last two seasons than in the prior three.
Moreover, Kane?s touches in the middle third of the pitch were significantly raised, while his 4.38 progressive carries per 90 in 2019/20 marked an all-time, and further reinforced his increased involvement (FBRef).
