In July, Tottenham manager Mauricio Pochettino was clear about the aim of the summer transfer window: bringing competition for places to his squad.
"When you play in the Premier League and Champions League, you need quality and numbers," Pochettino said. "To create a winning team, you need [the players] to feel the pressure. If I'm Harry Kane, Dele Alli or Christian Eriksen and there's no competition behind, it's normal to drop your motivation."
Spurs finished the summer with five new signings -- defenders Davinson Sanchez, Juan Foyth and Serge Aurier, goalkeeper Paulo Gazzaniga and striker Fernando Llorente -- while defenders Kyle Walker and Kevin Wimmer left the club.
