Portsmouth defender Ricardo Rocha has warned his side to beware Leicester's desire for revenge when they visit the Walkers Stadium on Saturday.Pompey, who are five points below the Foxes in the table, thrashed them 6-1 in the reverse fixture in September. [LNB]Rocha, 32, told BBC Radio Solent: "It was a good win for us and they'll be doing their best to forget it. [LNB]"But they're still a very strong team with good players and we must go there to win and play our game as always." [LNB]The former Portugal international continued: "It's a good stadium to play in, a good pitch, two good teams - it should be a nice game to watch.[LNB] We've had time to rest. We needed to recover and get ready for this weekend. Portsmouth defender Ricardo Rocha "This league is unbelievable and you never know what will happen, there are teams [like Leicester] who were at the bottom and now they've started winning games and are doing well." [LNB]Rocha will be reunited with ex-Portugal and Real Betis goalkeeper Ricardo Pereira on Saturday, after he joined the Foxes on a short-term deal in January. [LNB]"We played together on the national team and he is a very good keeper," said Rocha. [LNB]"He didn't get a good chance to play in Spain but with Eriksson he will find a way to return to form. [LNB]"Every player looks at the Championship as a difficult league with good players so it's good for him to come here and learn about English football and how to play here." [LNB]Pompey's 0-0 draw with Middlesbrough last weekend was their fourth game in 12 days and Rocha says the team were glad to have seven days off to recover this week. [LNB]"We've had time to rest. We needed to recover and get ready for this weekend. We have a difficult and important game now against a very good team," said the ex-Tottenham defender. [LNB]"We've had a lot of games and some of them were tough but we have to give our best to each other and we always have to try our best to keep winning these games."
