Dutch Player of the Year 2003, signed by Chelsea for £12million.
Over 100 Premier League appearances for Chelsea and a dozen England caps before Mourinho joined the club. Already club vice-captain when Mourinho joined - and captain Desailly retired.
£7million transfer had been agreed by Ranieri before Mourinho joined the club. At this point he was already the Czech Rep's number one keeper with two seasons' experience from Ligue 1.
Over 100 Premier League games for West Ham and had already travelled to the World Cup with England when Ranieri signed him for £7million.
Signed for Inter and brought into the first team by Roberto Mancini in 2007. Fell out with and was dropped by Mourinho several times over the two years they were at the club together, leading to his being sold on in 2010.
Signed for £9million from Lens after establishing himself as a Ligue 1 regular.
You got one! Given his first-team debut by Mourinho, for whom he played 18 games in three years. He played 34 games the season following Mourinho's departure.
The players I listed for Guardiola above were all brought through from the club academy where they had in most cases actually worked with him when he was coaching the B team. He gave them all their first-team debuts and many went on to be full internationals. Pedro - who you apparently dismiss as having not made the grade at international level - has 64 caps and World Cup and European Championship winners' medals alongside his three Champions Leagues.
