The CL is NOT where the big boys play. The group stages of the competition are a farce with greek sides, cypriot sides,
Ukrainian sides etc. Spurs will be one of the top 8 teams in the CL next season. The only thing that could do them is that they might get a really tough draw as they'll be low seeds. They have nothing to fear in the CL, the standard is vastly overrated. Just look at the semi final between bayern and lyon this season, mediocre sides...
