Nani admits Manchester United's clash at Manchester City next month will be a title decider.
United face City in a crucial derby clash at the Etihad on April 30 - with Nani and his team-mates desperate to avenge their 6-1 defeat at Old Trafford.
The playmaker told the Daily Star Sunday: "Yes, we must perform in that game, especially for our fans.
"As I have said, it may well be that it just comes down to who can handle the pressure on the day.
"And I know that my team-mates can deal with it, so we will see."
