Contador was handed a the ban by the Court of Arbitration for Sport [CAS] in February and was stripped of numerous wins on his palmarès, including the 2010 Tour de France and 2011 Giro d'Italia titles - after failing a test for the banned anabolic agent clenbuterol.
The 29 year-old last competed in the road Worlds in 2008 when the Spaniard hoped to add the world champion's rainbow jersey to his Vuelta a España and Giro triumphs. However, Alessandro Ballan of Italy took the honours in his homeland to deny the then Astana rider a rare hat-trick.
The rider suggested that he may compete in both the time-trial and road race at the Worlds. "I would like to do both," he said. "In the time-trial there are some steep slopes that I think could favour me, while in the road race there might be some riders who are better prepared than me," he said.
Contador, who joined Bjarne Riis's Saxo Bank team in 2011, has now targeted the Eneco Tour for his return ahead of the Vuelta and then the Worlds.
"I will be back for the Eneco Tour. For the first time, I can say that I will be at the Vuelta," Contador told Spanish radio.
The week-long Eneco Tour starts on Aug 6, one day after Contador's suspension ends, and will finish on Aug 12. The Vuelta starts six days later.
Contador will then set his sights on the Road Race World Championships in Valkenburg, Holland the following month.
"I would like to be part of the selection," he added.
Contador is currently without a team following his ban, although it is widely expected he will rejoin Riis on Aug 6 in Saxo Bank colours despite interest from as many as six other teams, including Spanish outfit Movistar.
"They [Saxo Bank] have supported me unconditionally throughout knowing everything that happened," Contador said.
"Both the manager and the sporting director have been fantastic, and that means a lot. I couldn't give a value to the support they have given me and that is why I can't see my future being anywhere other than Saxo Bank."
