Nicolas Jackson, despite his impressive physical attributes, continues to disappoint Chelsea fans with his persistent inability to convert crucial opportunities into goals.

The growing frustration among the supporters was palpable during the FA Cup semi-final against Manchester City, where the 22-year-old Senegalese striker missed three significant chances to score. His performance this season has been underwhelming, with a mere 32% conversion rate of 'big chances', placing him 25th out of 26 players in Europe's top five leagues who have taken at least 30 shots across all competitions. Only Darwin Nunez of Liverpool has a lower rate at 20%.

Jackson's pattern of missed opportunities and inaccurate shots was evident again in the recent match against Arsenal, where he failed to make a significant impact and missed a critical chance, hitting the side-netting. Chelsea suffered a heavy 5-0 defeat, marking one of the lowest points of Mauricio Pochettino's tenure as manager.

Despite scoring 13 goals and providing five assists this season, Jackson's numbers do not fully reflect the extent of his struggles. His performance is a far cry from the club's legacy of prolific strikers like Didier Drogba and Diego Costa, raising doubts about his ability to reach similar heights.

With Chelsea's #15 at the helm, the club's historic success in the striker position seems distant. Whether Nicolas Jackson ranks as Chelsea's worst striker is still debatable, but his current form certainly puts him in contention for this unwanted title.
