Mauricio Pochettino is worried he cannot count on all of his players and that it will grow into a problem after a last-gasp win over Wycombe that served as a wake-up call.
Tottenham’s manager made nine changes for the visit of the League Two club but admitted his second-string side were lucky not to lose this FA Cup fourth-round tie.
Twice on Saturday they trailed to a team 70 places below them in the Football League ladder and Tottenham were also 2-0 down at half-time, booed off by their own fans at White Hart Lane.
It took two late goals to see the Premier League team through, including a winner from Son Heung-min in the seventh minute of stoppage time that spared Pochettino an unwanted replay.
