I would say (partly from personal experience) that despite the macho stereotype, Latin males tend to express their emotions (especially sadness and affection) much more openly, but of course there's a range. Leo Messi in particular is almost childlike in that respect. Even Pep Guardiola broke down in uncontrollable sobs on the pitch when Barcelona won the World Club Cup Championship in 2009.

The thing is, these players are very close to their coach. They speak of him treating them like his sons. They are going to miss him terribly.
