Manchester United midfielder Anderson says he wasn't surprised by Porto's performance in the first-leg of their Champions League clash.
"I wasn't surprised at all," Anderson told reporters at Tuesday's pre-match press conference. "Porto have a lot of quality in the squad. A lot of them are South American, so they know how to play football."
The front three of Lisandro (Argentinian), Hulk (Brazilian) and Cristian Rodriguez (Uruguayan) were particularly impressive eight days ago, although Anderson is confident United can shackle Porto's attackers and book a place in the semi-finals for a third consecutive season.
"We might not have been at our best in the last few games but we have to go into this game confident. We have the will to win.
"Porto are certainly capable of producing another good performance. But we all know United need to play well and, most importantly, score goals. That's our objective and we're confident."
