Tottenham coach Juande Ramos won't explain his decision-making to striker Robbie Keane after his strop on Sunday.

Keane had scored Spurs' goal and the match was balanced at 1-1 against Manchester City when Ramos opted to substitute the striker, prompting Keane to tear off the captain's armband and throw his jacket to the floor when he reached the bench.

"I will not speak to Robbie about why I substituted him," said Ramos. "Will I do it again? Of course. I make changes depending on the requirements of each game. I don't worry about [tantrums]. If players want to get angry it is not something I worry about."
