Strachan, who missed out on a fourth straight Scottish title on the final day of the league season last weekend, took a bow and received a warm round of applause from the Celtic fans before the charity match.
Strachan made a surprise appearance at the tribute match to take a bow and was given a warm round of applause by home fans who had not been unanimous in their support for the former Aberdeen and Manchester United midfielder despite his success with the club.
The bulk of the Spanish team wasn't even alive the last time that happened more than 30 years ago, at the 1982 World Cup, when it lost to West Germany (2-1) and then limped out of the tournament following a 0-0 draw with England, becoming the first host nation ever to bow out of soccer's biggest showcase in the first round.
