Gerard Pique has admitted he was still nervous meeting Roy Keane years after leaving Manchester United.
Pique spent four years at Old Trafford between 2004 and 2008. He made a total of 23 appearances for the club before returning to Barcelona, where he was brought through the youth ranks ahead of his decision to sign for United.
The centre-back has enjoyed great success since leaving United. Pique, 35, has won eight La Liga titles, three Champions Leagues, seven Copa del Reys, six Spanish Super Cups and three FIFA Club World Cups during his stay at the Nou Camp.
