Chelsea signing Diego Moreira has touched down in London.
The former Benfica prospect has joined Chelsea in a free transfer and is due to collect his UK work permit this week.
The 18 year-old winger played for Portugal at this summer's U21 Euros.
Moreira is likely to spend the season with the club's U21 team as the club continue to strengthen.
He made two senior appearances for Benfica last season.
