Kolo Toure has begun the mind games between Arsenal and Manchester United by claiming their opponents are the favourites to progress from their UEFA Champions League semi-final meeting.
The Gunners booked their place in the last four of Europe's elite competition after a 4-1 aggregate victory over Spanish side Villarreal.
United, meanwhile, claimed a hard-fought 3-2 aggregate success against Porto, with winger Cristiano Ronaldo netting the decisive goal in the second leg.
Toure is now eagerly anticipating Arsenal's clash versus the European champions, having defeated their rivals in the Premier League earlier this season.
He said: "We are in the semi-final. We have fresh players. We played with a new defence today [Wednesday] and we did very well.
"Now we need to get ready for Saturday against Chelsea. We will have to face (Didier) Drogba, who is always good against us.
"For the Champions League, I think we are not favourites as United are the champions.
"However, they know we can beat them, so we are looking forward to it. Bring them on."
