Dimitar Berbatov admits he suffers nerves ahead of playing for Manchester United.
The Bulgarian international revealed: “I am still nervous but, when you play for the biggest club in the world, you are sometimes shaking before you go on the pitch.
“Sometimes I show it with my hands or by screaming on the pitch but sometimes it’s the other way around.”
Berba has enjoyed a solid start to his United career with 14 goals in 42 appearances this term.
His low-key goal celebrations led to suggestions he did not care enough about playing for the champions.
But the former Spurs man insisted: “I know people sometimes say I don’t mind what happens but, trust me, I feel it very hard.
“If I don’t show it on my face, inside I’m a really happy guy. Sometimes I get frustrated with myself because, in some games, I haven’t shown my 100 per cent.
“Everyone has the right to an opinion. Half the people might like me, the other half might not — I just try to make the non-believers into believers.”
Berbatov insists he has all the same fighting qualities as his team-mates.
He added: “When you’re in the tunnel and you hear ‘Please welcome the champions of England, the champions of Europe and the champions of the world’, you believe you’re going to crush anybody in your way.”
