Toby Alderweireld has claimed that there is no chance of Tottenham Hotspur becoming complacent in their climb up the Premier League table.
Spurs are unbeaten in the league since the opening day of the season and can move within two points of the Champions League qualification places by beating West Ham United on Sunday.
However, Alderweireld insists that the squad will never become over-confident under the guidance of Mauricio Pochettino.
"It's a big challenge because West Ham are playing very well and they are near the top places in the league with us," the Belgian defender told the club's website.
"They're a very good team so it's going to be difficult for us, but we are in a good moment as well. Everybody is doing well and there is a lot of confidence among us, but I feel we are not over-confident.
"We are where we are because we work hard and when we do that our quality can make the difference. The first thing we have to do is work hard and that's what we're going to do on Sunday."
Spurs have beaten West Ham just once in their last five games.
