Mauricio Pochettino is calling for Tottenham Hotspur to make several signings in January.
Spurs didn't add a single player during the summer window.
"In football you always need to think you can improve, and you need to try to improve your squad.
"I've tried to explain before what happened in the summer, the circumstances. But if you say to me we were so clever and are geniuses because we didn't sign [anyone], and now after nine games it's the best ever start in the Premier League, I'm not going to be the kind of person to say: 'Yes, we are geniuses.'
"We couldn't sign for different circumstances, but we wanted to sign. I think it's maybe a coincidence, or we worked a lot, or because we're clever, but to be honest always you try to sign.
"Now January will come and we're going to try to sign. I think it's not only us -- all the clubs and managers want to sign players, must refresh the squad.
"We need to try again in January or the summer if we want to move on the team and the club."
