Dele Alli is not guaranteed to start tonight as Tottenham Hotspur host Bundesliga leaders Bayern Munich in the Champions League.

Stan Collymore has hit out at struggling Tottenham Hotspur star Dele Alli, telling the England international that it’s time he grows up and accepts responsibility for his fall from grace in explosive comments printed by the Mirror (1 October, page 51).

Two years ago, Alli looked to have established himself at the very top of the European game after scoring twice in a famous 3-1 win against Real Madrid in the Champions League group stage. At the time, the former MK Dons starlet was one of the first names on the team-sheet for England and a goal-scoring midfielder with genuine world-class potential.

These days, however, the 23-year-old appears to be at a crossroads with his development stalling and the goals drying up. Alli, who has endured his fair share of injuries too, is no longer a guaranteed starter for club or country.

But Collymore, the former Liverpool and Aston Villa striker, is in no mood to put an arm around the shoulder, telling Alli that he has to take a long look in the mirror as he looks to rebuild his ailing reputation.

“There obviously are (issues that need addressing). Dele Alli needs to stop being a little kid, grow up and accept responsibility so he can go on to fulfil his promise,” Collymore said.

Bayern Munich at the Tottenham Hotspur Stadium is perhaps the perfect stage for Alli to silence the doubters and prove that he still deserves to be a key player under Mauricio Pochettino.

But it is a sign of how far he’s fallen that the 23-year-old is now far from guaranteed to start against the Bundesliga champions.
