European champion Barcelona continues its quest for a second consecutive treble when Gary Neville's off-form Valencia visits the Camp Nou in the first-leg of their Copa del Rey semifinal Wednesday. Valencia's run to the last four of the Cup has been the only positive of a difficult start for the England coach in his first managerial role. A first defeat at home in La Liga since November 2014, 1-0 against Sporting Gijon Sunday, stretched Neville's winless streak in La Liga to eight games and left Valencia just five points above the relegation zone. Neville's men face the most daunting task possible if they are to reach the final for the first time since 2008 against a Barca side that hasn't lost in 26 matches in all competitions. However, Neville insists he is embracing the challenge of returning to the scene of one of his greatest triumphs where as a player he won the Champions League with Manchester United back in 1999. "I can't wait for Wednesday night, and I think the players will be the same. These are the moments you live for as a coach and a player," he said. One of Neville's boldest moves has been to name top scorer Paco Alcacer captain in place of Dani Parejo and he is hopeful the Spanish international will be fit to feature after two weeks out with an ankle injury. "By Tuesday we'll have a full complement of players, Paco is looking good and is back running again." The visitors could also hand debuts to Denis Cheryshev and Guilherme Siqueira after they sealed loan deals from Real Madrid and Atletico Madrid respectively until the end of the season. Cheryshev's inclusion in the Real team for its Cup opener at Cadiz saw it thrown out the competition as he was suspended for an accumulation of yellow cards last season. However, he is free to feature at the Camp Nou. "Barcelona are a great opponent, but Valencia also can also do some damage," said the Russian international. Barcelona boss Luis Enrique has a fully-fit squad to choose from and is likely to rotate after his side showed growing signs of fatigue from its demanding January schedule in edging past nine-man Atletico Madrid 2-1 Saturday. "It suits us to have four days rest before hosting Valencia," said defender Javier Mascherano. "We have managed to keep winning and we're in an ideal situation, but in any moment it can slip away so we have to keep going." The other semifinal sees Sevilla entertain Celta Vigo in their first-leg Thursday. After a difficult start to the campaign, Sevilla has won 11 consecutive games in all competitions at home. Celta caused the shock of the quarterfinals by knocking out Atletico Madrid and will be boosted by the return of Spanish international Nolito.
