Mauricio Pochettino has insisted that Leeds United allegedly spying on Derby County ahead of tonight’s Championship game was “not a big deal” and was commonplace in Argentina.

Derby announced in a statement today that police officers found a man “acting suspiciously” outside their training ground yesterday morning, and that that man was an “employee of the footballing staff at Leeds United Football Club.” Leeds are of course managed by Marcelo Bielsa, the man who discovered a teenage Pochettino, coached him at Newell’s Old Boys and subsequently at Espanyol and the Argentina national team.

Pochettino has spoken plenty of times in the past about his debt to Bielsa, who he has described as his reference, his “football father” or his “second father”.

But today he was asked to comment on what appears like sharp practice from the team Bielsa now manages. And Pochettino’s response was that trying to watch an opponent train, while not exactly in the rules, was not uncommon for managers in Argentina. Especially operating back in the 1980s and 1990s, back when Bielsa first met a teenage Pochettino, in a league where almost anything went.

“It's nothing wrong with finding information about what the opponent is doing,” Pochettino said. “30 years ago it happened in Argentina. Not only Marcelo, all the managers. When I was 17, 18, 19-year-old all the managers like [Carlos] Bilardo or many, many others used to send people to watch training sessions. Here it's a bit weird, but it happened in Argentina.”

For Pochettino, trying to get one over an opponent is just part of the Argentinean way. Like at the 1966 World Cup. “I remember in 1966 World Cup, how did the Argentina team behave? Remember, we always wanted to be more smart than the opponents. It's not a big deal what happened.”
