Cascarino was not impressed with the display produced by Alli during Tottenham’s 1-0 defeat to Bournemouth away from home at the Vitality Stadium in the Premier League at the weekend.
The Times and talkSPORT pundit believes that the England international midfielder has failed to make an impact on too many games this season.
Cascarino has also made a comparison between Alli and Arsenal attacking midfielder Mesut Ozil and Manchester United’s Alexis Sanchez.
Cascarino wrote in The Times: “At Tottenham Hotspur, Dele Alli has been the biggest disappointment.
"The England midfielder was poor again against Bournemouth on Saturday and has failed to leave his mark on too many games this season.
"Huge amounts of money have been invested in Sánchez, Özil and Alli without much return.”
Harsh on Dele Alli
Alli is only 23 years of age, and although the England international has not been great this season, the midfielder has shown in recent years what he is capable of and the quality he possesses.
Moreover, Tottenham paid Milton Keynes Dons just £5 million in transfer fees when they signed Alli back in February 2015, as reported by BBC Sport.
There is no doubt that the 23-year-old has a bright future ahead of him, and the midfielder will get better in the coming years.
