Manchester United are expected to welcome the Silva twins, Rafael and Fabio, this summer.

The Silvas caught Sir Alex Ferguson's eye at a youth tournament in Hong Kong in 2005 during United's pre-season tour to Asia and signed pre-contract agreements when they turned 16 in July 2006. The twins excelled for Brazil in the Under-17 World Cup finals in South Korea last August, with Fabio, the captain, finishing as his country's joint leading scorer.
