Kolobnev finished a close second to Alexandre Vinokourov last year but was only 11th this year, while Rodriguez was further back in 26th place. Kolobnev admitted he missed the decisive attack by the Schlecks on the Cote de la Roche aux Faucons.
"I wasn't very focused in the very moment when the Schleck brothers attacked. It was a fatal distraction, which conditioned my race," the Russian national champion admitted in a statement issued by the team.
"I'm sorry because I think I was in a good shape, but for a rider like me, it was important not to lose the best riders' wheel. When I lost them, it was already impossible to close that gap. I'm really sorry, I'm very disappointed with my race because I did everything to be in my best shape for this competition. I hoped to reach a better result, because my shape was good enough to do so."
Like many riders, Rodriguez was affected by the very high pollen count in the Ardennes caused by the hot weather and lack of rain in the last few days.
"For me, it was a bad day. I can't say why, but the fact is that today I felt empty, with no energy. I think I suffered the flower-dust allergy more than I expected," he said.
"It was very hot, and this created a particular weather condition which I suffered a lot. In fact, I couldn't breathe very well. In the end, when I have to change my rhythm, I couldn't because I...
Brothers have no regrets after finishing second and third
Fränk and Andy Schleck were bitterly disappointed to lose to Philippe Gilbert at Liège - Bastogne - Liège, but believed they did everything they could to try and beat him in the finale of one of the toughest editions of the race in years.
The Leopard Trek team worked hard to isolate Gilbert and then Andy lead Fränk as they made a double attack on the Cote de la Roche aux Faucons. However, Gilbert was the only rider able to go with them and then made his own attack on the Cote de Saint-Nicolas to stamp his authority on the brothers and show them who was the strongest in the race.
The sprint in Ans was an easily executed formality for Gilbert, and he pulled out several metres on Fränk, who finished second and the more fatigued Andy, who was third.
"I don't think we could have done any thing differently," Fränk conceded in a video interview just after his brother had spoken to camera.
"We attacked together, which we don't normally do. He was unbeatable - the only one who could follow us (on the Cote de la Roche aux Faucons) and there was nothing else we could do."
"We have no regrets and that's the most important thing. He just wasn't beatable."
