Mauricio Pochettino says there are no regrets over Tottenham Hotspur's quiet transfer window.

Spurs, currently fifth on the Premier League table, did not sign a single player in the summer.

"Look I told you from day I am never going to charge the walls of my boss. He's my boss, he's the owner of the club," said Pochettino ahead of Saturday's London Derby against West Ham United.

"It was difficult to sign the players that we needed, that was impossible and I am happy with the squad that we have, 25 players, we have no regrets and we are happy.

"When we started the season with three wins and we were top of the table I think people were talking in a different way and saying how clever Tottenham were to keep all their squad from last season.

"I have to remind everyone this is our best start after eight games. The perception changed when we lost to Inter Milan and Barcelona in the Champions League but we have one more point than last season.

"I am not happy with that because we are fifth in the table and the ambition is to be on the top but at the same time we are realistic after all the circumstance we suffered in the summer with the World Cup and everything.

"But we keep fighting and we are very close to the top of the table."
