Mauricio Pochettino insists Tottenham's crunch clash at Manchester City on Sunday will be important to the English Premier League title race but not decisive.

Spurs head to Manchester knowing victory would pull them four points clear of Manuel Pellegrini's side in the race at the top of the table.

(How important is Sunday's match?) "For me, every game is very important because to arrive at the end in the position that we are or improve our position you need to win games. But it's not decisive. It's important, very important but it's not the last game that you need to achieve or not after 90 minutes. It is not the last game. But I think it is a very important game. And we know, they know, we are in a position where there are 13 games ahead, but after the next game it is 12 and we are going into the more important period in the league."

(How important was the 4-1 win at Manchester City at the end of September, especially considering that Tottenham had made a slow start to the season?)

"Yes, was a very important game for us. Was a very important victory and I think that gave to us more belief and trust in ourselves and our quality. I think it was one of the important games from the beginning of the season."
