Sir Alex Ferguson missed a Manchester United first-team match to scout David de Gea, who was playing for Atletico Madrid, in Spain before signing the goalkeeper, whilst he also invited him to his home to have lunch after he signed for the club.
Ferguson signed De Gea for a fee of £18.9million from Atletico Madrid in the summer of 2011 and he's won the Premier League, Europa League, FA Cup and League Cup during an over 11-year successful stay in Manchester.
Erik ten Hag has stuck with De Gea as first-choice goalkeeper this season and the Spaniard is one of two players who have won a Premier League title with United to still play for the club (the other player is Phil Jones).
