The Portuguese coach, who witnessed his side clinch a 3-2 win over Manchester United at Old Trafford on Saturday, has insisted that qualifying for the Champions League is the club's main priority.
"I don't think [we can win the league]," Villas-Boas told Sky Sports News. "It is still a long way to go. We are just starting in the league.
"It is an important win for us, for the impact it has. But we are a long way and we have to continue to make progress. So we have to get as many points as possible to reach the objective for the season which is Champions League qualification."
