Cobo has been suss since he the Saunier Duval days when he allowed Piepoli to beat him in the infamous Ricco tour. Ricco predicted that Piepoli would win on the Hautacam as a reward for helping him. The other two got nicked for EPO but Cobo didn't somehow. Those three were sprinting up the mountains like goats, riding
Evans, Schleck etc off their wheel with ease.
He latterly spent a year at Caisse d'Epaigne when he did nothing at all. Moved to a Spanish team and won the Vuelta. Nothing conclusive but definitely high on the radar. Rarely does well outside the national borders. Wiggins has shown that you can do well in races before the event you're targetting so I find his dreadful form prior to 'peaking' at the Vuelta slightly hard to believe. But I'm not a hater or a witchfinder-general!
