Manchester United defender Lisandro Martinez says they can be happy after victory over Europa League opponents Real Betis.

United won the first-leg of the round of 16 tie 4-1 at Old Trafford.

Lisandro said, "We did an amazing job today, especially in the second half. We created many chances and we scored. It's a good result but it's not done yet so we have to keep going and be ready [for the second leg].

This is what we are, we have a really good mentality. We always want to win games. The game against Liverpool is not what we are and yes, we were in shock, because it was a really bad result for us. We said what we had to say and now we have to keep going.

On the return fixture next week, he added: "It's another game and we have to go with that mentality again. We have to be ready because they play really good football, especially at home."
