The Red Devils are preparing to welcome the La Liga outfit to Old Trafford for the second leg of the tie after the goalless draw in Spain last month.
Manchester United warmed up for the game by claiming an important 2-1 win over bitter rivals Liverpool FC at Old Trafford in the Premier League on Saturday afternoon.
Jose Mourinho’s men now face two crunch cup ties – the first against Sevilla, and then the FA Cup quarter-final tie against Brighton and Hove Albion at Old Trafford on Saturday.
And Red Devils playmaker Mata has talked up the importance of not underestimating their Spanish opponents in the return leg of their Champions League tie on Tuesday night at Old Trafford.
Writing in his personal blog, Mata said: “After a week with two big games, what can we say about the next one.
“First against Sevilla, on Tuesday, when we also need the support from Old Trafford to get the win and make it to the next round.
“For the club and for everybody it’s important to move forward in the Champions League and to feel that we are up there, alongside the best teams.
“I’m sure Sevilla feel the same way, and they already showed in the first leg that they have players and football to make things difficult for us.
“They’ve been performing very well in Europe for many years and they are very competitive. I hope the Red Devil family can enjoy a great night.”
Manchester United are currently in second place in the Premier League table as they look to try and finish in the top four this season.
Mourinho’s men ended up in sixth place last term but booked their spot in the Champions League group stage for this season by winning the Europa League in the Portuguese coach’s first campaign in charge last year.
