Tottenham's goal drought shows no sign of ending, and according to Sky Sports, Paul Merson believes Roberto De Zerbi's public criticism of his own squad is a cause for concern.

Spurs were held 0-0 by Nottingham Forest at the weekend, extending their wait for a first Premier League goal of the season. After the match, De Zerbi didn't hold back, blasting his forwards for failing to make "better decisions" in front of goal. The Italian also took aim at his medical department, admitting he was "not happy" with the club's fitness staff amid ongoing injury concerns.

Merson says that kind of public airing of grievances so early in a manager's tenure is worrying, suggesting it could signal deeper issues behind the scenes at Spurs as De Zerbi looks to get his tactical ideas across to a team still searching for cutting edge in attack.

With Tottenham yet to find the net in the league, the pressure is mounting on De Zerbi to fix the problems quickly — both on the training ground and, it seems, within his own dressing room.
