Pochettino never coached in South America though, he started at Espanyol and was used to the issues of a modern European dressing room. Gallardo has not coached in Europe, and frankly yes, it is a different level, especially given the differences in dressing room culture between a culturally monolithic Argentina and somewhere like Spurs. He might well be learning English, but I do not want to take a flyer on a guy who's never had to juggle a dressing room of 5 different languages and multiple ethnic groups. That stuff does matter, and not everyone can do that. Spurs are a big enough club to not be someone's test run on those issues. He might well be a very good coach, but I want to see him do it at a higher level of difficulty with the kinds of challenges that he will face in Europe, before he comes to Spurs.If it's a cultural thing, I could understand, although Poch didn't turn out too shabby. And he had a fraction of the resume Gallardo has when we appointed him. If it's "because it's the Argentinean league," I think you are being too dismissive of it. It is a very tough league and the Copa Libertadores (which he won twice) is nothing to sneeze at either.
Personally, I don't think we have the luxury to wait for him to prove his bona fides elsewhere. He's not going to take a Bournemouth or Salernitana level job. When he comes to Europe to manage it will be a big team. Not necessarily elite team, but it won't be a minnow. And it won't be in Austria, or Belgium, or Switzerland. So might as well take advantage of the opportunity and get to him first. He is learning English too while he is taking time off.
