I don't agree really. Plenty of negatives playing for the English NT. One of the most anti-football establishments around. A team like Nigeria still have that underdog bite to them, unpredictability and hunger about them whereas England are in a constant stream of mediocrity whilst also having the platforms t be successful and being fairly well established as a NT for many years; coupled with constant media lashings and all the pundits we have to listen to for an opinion on football.
He plays in England all year around, for a big team with constant pressure to perform. Going to a new environment and experiencing new methods and ways of life seems a better experience to me.
