I did consider Uruguay but noticed that only two teams have ever won the trophy bar a few odd teams throughout history. It does appeal because it may be difficult but worried that the league itself may be a task in itself nevermind the Copa Libertadores, as I'm sure it would be difficult to try and compete with the budgets of Brazilian and Argentine teams.
I never considered the length of time it takes for the competition, read online it takes place over 10 months. I had thought of Belgrano in the First Division in Argentina as they have never won any trophies and I wanted to create history with them. Also considered Almagro in the second tier as they are from Buenos Aires. Think I may have to look somewhat lower than Belgrano to make it an interesting save!
