Juan Mata wants Manchester United to remain focused as they take on Tottenham and AC Milan during their preseason.
United picked up an impressive win over Inter Milan, dominating the game in a 1-0 victory.
But Mata does not want the team to get carried away, as he believes there are many tougher tests ahead.
The Spaniard said the following at an Adidas media event in Singapore: "Tottenham is going to be tough, [AC Milan] is going to be tough.
"So we still have a few difficult games but [we planned] to use these games to get ready for the Chelsea game, which is our first official game, and that's the important one and the one that we have to be ready to win."
