Tottenham Hotspur crashed out of the Champions League group stage on Tuesday evening after failing to overcome AS Monaco at the Stade Louis II and manager Mauricio Pochettino has admitted that it is because of a shortage of quality options within his own roster.
The simple solution for Pochettino, therefore, is to turn to upcoming transfer windows and adopt an aggressive recruitment drive in order to continue to shorten the gap between themselves and accomplished continental sides.
Spurs, after all, pushed Leicester City almost all the way in the 2015/2016 Premier League title chase, before slumping into third place. This season, they remain unbeaten in the league, but are still four points adrift from pace-setting Chelsea at the top of the table.
Players like Danny Rose, Kyle Walker, Harry Kane, Jan Vertonghen and Toby Alderweireld have performed well so far this season and the club still have other name players like Christian Eriksen, Hugo Lloris and Dele Alli to call upon, but they lack the squad depth that their rivals possess.
Commenting after the 2-1 loss at Monaco, Pochettino confirmed to Sky Sports that changes could be made: "It is good for us to learn from this for the future if we are going to be in the Champions League next season and try to compete in that and the Premier League, maybe we need to make changes.
"It was a good challenge for us to show the real level," he said. "It's true after two-and-a-half years we closed the gap between the top clubs but to be competitive in the Champions League and Premier League we need to show more - and maybe to add real quality."
Though Harry Kane has been linked with a transfer away from White Hart Lane, most notably to Manchester United, the club have been rumoured to be preparing moves for players like Isco, at Real Madrid.
Additionally, Spurs are apparently studying Ante Coric of Dinamo Zagreb, a player who has been likened to former Tottenham star Luka Modric.
Though the Lilywhite North Londoners will be disheartened by the loss to Monaco, they have little time to mourn as they are now heading into a vital Premier League match against an in-form Chelsea side, at Stamford Bridge, no less.
The game kicks-off at 17:30 on Saturday, November 26.
