Robbie Keane is convinced Tottenham's summer spending is still not over.

Spurs have signed Gareth Bale, Darren Bent and Younes Kaboul so far this summer in deals that could eventually be worth more than £30million, and Kevin-Prince Boateng has been tipped to be the next to join.

Keane, 27, hopes the improvement to the squad means Spurs can go better than their fifth-placed Premier League finishes in the last two seasons.

After scoring in the pre-season friendlies against Stevenage and St Patrick's, Keane said: "With maybe a couple more additions we will have a great chance."
