He told manutd.com: "Listen, about United supporters, I have so many things to say, but so many good things because this season had been very difficult, very difficult for all of us. For me, my start was difficult, but they were always behind us, always behind me and it was incredible. I remember one game against Palace. It was not our best game. I think it was maybe our worst game of the season, but they were there.
"Not only that game, these guys, they are behind us in the good and the bad moments. And sometimes we feel like, even if it's difficult, we know we have our soldiers behind us. So on Saturday, I would love to promise them we're going to win. I would love to say we're going to win, but what I can promise Saturday, we're going to die on that pitch because we know they're going to stay behind us. This motivation is extra motivation for us. So when we will go, they're going to give everything, everything.
"For me, I have played for good clubs, many clubs. What we faced this season was difficult. But the only positivity I will say about this season is our fans because they were always with us. Bad moments, bad, bad games, difficult situations, they were always there and I hope, I hope it will come, but I know also when we're going to win, we're going to have that joy together.
"But not only for the FA Cup, you know, because everything in life is temporary and better days, better days will come. Now we are living in Manchester. It's raining a lot but it will not rain forever. Sun will shine and when you shine, I hope we're going to be there together. And thinking about those moments we pass, those difficult times we pass together. It's just going to be like 'we did it' - and we did it together."
