Juan Mata says Manchester United know their 2018/19 campaign wasn't good enough.

The Red Devils will play in the Europa League next season after finishing in sixth-place in the Premier League.

"We know that last season wasn't good enough," he told media at an Adidas event in Singapore.

"So we need to improve, we need to try our best in this upcoming season.

"What we have to do is raise our level and compete and let's see where we end up.

"You know, the level in the Premier League is getting better every single year.

"All the clubs have been bringing (in) very good players, so we need to try to be at our best."
