The Lone Star have named 12 overseas-based players in the squad for the game in Cameroon, but the Greece-based pair of Kelvin Sebwe and Oliver Makor have both been omitted.

Nagbe spent a week in the UK during which he spent a day at Manchester United, where he met Feguson as well as several players including Christian Ronaldo and Wayne Rooney.

"One of the things I learnt from Sir Alex is how to prepare my team for both home and away matches," he told BBC Sport.

"I have to change tactics especially that we are playing away.

"I need players who can work for ninety minutes and the system I'm to play is a full endurance system that's why I've selected this batch of players."

However Nagbe made it clear that Sebwe and Makor both remain in his plans for the future.

The coach picked up several other ideas on his visit to Manchester United.

"He (Ferguson) talked to me about some team strategies," he explained.

"One of his deputies spent two hours with me in the classroom talking to me about psychology and tactical aspects of the game.

"I'll be dealing with my players in a new way."

Nagbe also feels that just shaking Ferguson's hand helped him as a coach.

"When I shook his hand it was like the magic was going through his fingers into my blood."
