I saw quite a bit of that Hamburg 1996 tournament. I was very very impressed with Carretero. He was particularly efficient when serving at the ad-side. His kick.serve had wicked side-spin, which forced his opponents way out of court to retrieve his serve. He then used his big forehand to play for the crosscourt winner on the next shot. It worked wonders, really.
I remember the Eurosport commentators stating that this guy was simply too talented for Corretja - I bet they would have been surprised to learn that it was Corretja who went on to greater things, not Carretero.
A lot of people predicted big things for him after that tournament. Tennis Magazine even predicted that he could do big things at Wimbledon. As we all know, nothing happened.
Carretero used to play juniors with Corretja and Costa and had a lot of talent, but he had knee problems and the first one held him up when he played on the circuit.
Yes, the Eurosport commentators would be surprised for sure that Corretja went further especially then all he had was a slice backhand and couldn't or wouldn't come over the ball.
Then Roberto got injured again, had a good time and piled on the beef.
