Tottenham Hotspur have a huge rebuilding job to do.They have burned through four head coaches in 12 months and narrowly avoided relegation. Roberto De Zerbi has had a positive impact since he joined in March despite inheriting an injury crisis after the final-day win over Everton that Spurs only have “10, 11, 12 players good enough to stay”.The squad is unbalanced and The Athletic reported earlier this week that signing a new left winger and central midfielder are high on the priority list. There is a lot of uncertainty around the futures of Guglielmo Vicario and Richarlison while there is a strong chance captain Cristian Romero will leave.There are nearly 30 senior players with highly-rated academy graduates and talented prospects returning from loan moves.Spurs are expected to sign Marcos Senesi and Andy Robertson, but they have been left out of the breakdown below because those deals have not been completed. Randal Kolo Muani has been omitted following the expiry of his loan deal, but Joao Palhinha is included because Spurs are discussing signing him permanently from Bayern Munich.Here, The Athletic breaks down the state of Tottenham’s squad and what should happen next.GoalkeepersGuglielmo VicarioAge: 29
