We can be suspicious, but without proof we have to assume they are not doping. It's not like Lutsenko has come from nowhere, he's been a pro for 7 seasons now I think, and has a lot of decent wins, i.e. something like 25 wins, which for a rider who isn't a specialist is pretty impressive. Most of his wins come in the early season too, he's obviously a rider who likes to start his season strongly.
