The two Spaniards have formed a deadly partnership at Old Trafford over recent weeks.
The Spanish duo have been in inspired form over the last few weeks, with both having scored braces in United’s last two games to help their side to victories and third place in the Premier League table.
The pair are good friends having years spent years rising through the youth levels for the Spanish national team together, and Mata believes it is that close relationship that has led to them having such a good understanding on the pitch.
"I think it’s because of the relationship we’ve had over the years and because we understand football and life in more or less the same way," he told ManUtd.com.
"I think we play well together because we understand each other and sometimes without speaking or looking we know where we're going to pass or where we're going to move on the pitch.”
Mata was the match-winner in the crucial victory over top-four rivals Liverpool prior to the international break, with the first of his two goals on that day being set up by Herrera.
He then returned the favour in the 3-1 win over Aston Villa when he played in his compatriot in injury time so that he could score his second goal of the game and wrap up the victory.
As far as Mata is concerned, the first goal at Anfield is a perfect example of their telepathic understanding on the pitch.
"The first goal at Anfield is a good example of that [the telepathy],” he added.
“He controlled the ball, turned and knew where I was already running to and he put the ball there. Ander is a quality player and I’m very happy he’s here and playing and performing well."
