And Mata says that he is already looking forward to the new season with United and is optimistic about the new campaign.
Mata wrote on his blog on Monday: “I’m looking forward to the next game in Old Trafford. I know it won’t happen in the next few months but playing in this stadium with this crowd is amazing… You never get tired of it…
“We wanted to finish the season at home with a win against Arsenal, in order to keep fighting for the third spot, but we couldn’t make it.
“We know we have played very good games this season but at the same time the team and the fans have had to cope with tough moments, and even so they have shown unconditional support. This union with our fans will be the key to celebrate titles soon. They deserve it. As every year, the lap of honour after the game was touching.”
He added: “The season is coming to an end and I want to tell you that the farewell in Old Trafford gives us strength and makes me feel very optimistic.
“Playing at this stadium for this loyal and tireless crowd keeps getting you goose bumps. Thank you once again. We hope you can enjoy good times the next season.”
Manchester United, who have secured a top-four finish during Van Gaal’s first season in charge at the club, travel to Hull City in their final Premier League game next weekend.
