Preparations for a World Cup can be nerve-wracking, but the mood in the Nigeria camp is far from dour.
"We have a lot of great players who have a lot of personality," vice-captain Ogenyi Onazi told BBC Sport before Nigeria's friendly against England at Wembley on Saturday.
"We have talents outside of football. I play the drums, I play the bass guitar."
The Super Eagles have created a buzz in London, with hundreds of fans queuing to buy their kit, which has now sold out.
"It is a game everybody has been looking up to. Everyone is waiting for this game," said Onazi.
"Playing at Wembley is something everyone is dreaming of. For me it will be the first time.
"We are humble, we respect England and we want to do our job. After the game we will see who takes the day."
Nigeria play the Czech Republic on Wednesday, the last of their warm-up games before the World Cup in Russia starts on 14 June.
Nigeria, who were knocked out in the last 16 in 2014, face Croatia on 16 June, Iceland on 22 June and Argentina on 26 June.
