Dele Alli has established himself as a key figure in Mauricio Pochettino's Tottenham Hotspur team, but he has not been as influential in the early stages of the season.Despite scoring three goals and creating one assist in seven appearances in all competitions, Alli has not been at his best.In midweek, Pochettino opted to play the England international against Barnsley in the EFL Cup in order to give the midfielder an opportunity to regain some form.The 21-year-old seemed to answer the critics by scoring the one and only goal in the third-round tie, but the fans were not convinced by his performance on Saturday afternoon.Tottenham ended up edging to victory in a 3-2 triumph over West Ham United at the London Stadium, with Harry Kane scoring twice and Christian Eriksen also getting on the scoresheet.Even though Alli provided an assist in the eventful match, which saw Serge Aurier sent off, some fans were disappointed with the player's display.
