We examine the impact of football player migration on their origin countries" international football performance. In our model, players acquire superior skills in foreign clubs, so emigration of players improves national team performance. We have collected information on the club of employment of national team players for most countries in the world. We have constructed an original migration index, weighting each emigrant player by the quality of his club of employment. We find strong and robust support for the theoretical prediction that migration of players to foreign leagues improves their origin countries" international football performance.
