Cristiano Ronaldo has warned holders Manchester United that Champions League quarterfinal opponents Porto will be no pushovers, ahead of Tuesday’s first leg clash at Old Trafford. “Porto are a very good team,” said Portugal’s World Player of the Year. “They are top of the league back home, ahead of Sporting Lisbon and Benfica and we know how strong they can be.” But Ronaldo, who scored twice in the dramatic 3-2 win over Aston Villa that sent United back to the top of the Premier League, is confident enough to predict that United will reach the last four “The good thing is we have two games against them and I feel that will be enough to get us through,” he said.
