Unai Emery looks set to ring the changes for Valencia's trip to Sporting following their Champions League stalemate with Genk. One player certain to miss out is midfielder Mehmet Topal, who will be out for up to a month after suffering a shoulder injury in Los Che's disappointing 0-0 draw during the week. Midfielders Ever Banega, Dani Parejo, Sofiane Feghouli and goalkeeper Diego Alves were also brought in for the European tie, and Emery will now decide which ones to retain, having dropped stopper Vicente Guaita to the bench along with Pablo Hernandez, David Albelda, Tino Costa and Jonas Goncalves. Roberto Soldado will be the first name on Emery's team sheet having scored four goals in helping Valencia pick up six points from their opening two games. Los Che's toughest challenge could be avoiding complacency against a side who are yet to register a point ahead of a testing run against Barcelona and Sevilla in the league and then Chelsea in the Champions League. Emery told the club's official website: "Tomorrow's (Saturday) game is a difficult one. We have started the league season in good form, with six points from two games, but we are visiting a team who have always had good performances against us. "Sporting need to play at the limit, because they have yet to take a point. We should show plenty of character, because this is an attribute that has been key in our results so far. "We also need to improve on the pitch. We are optimists and realists at the same time: This game is important for the path that we want to take in the league." Best Bet: Roberto Soldado to score a brace - 5/1
