Barcelona welcome Valencia to the Nou Camp on Sunday - live on Sky Sports 3 HD from 7.15pm - looking to get their La Liga title challenge back on track. Luis Enriques side have lost three of their last four matches in all competitions, exiting the Champions League to Atletico Madrid and seeing their lead at the top of the table cut to one point after defeats to Real Sociedad and Real Madrid.They remain favourites in the league and face Sevilla in the Copa del Rey final, and while Real Madrid kept the pressure on in La Liga with a 5-1 victory over Getafe on Saturday, Enrique believes his side will put their difficult run behind them when Valencia come calling. We have to lift ourselves up and focus on what we have ahead of us, he told reporters. And that means two very attractive competitions that we are still involved in.We have to forget the past. It wont be easy, and we are going to need the fans support more than ever. Its at difficult times like these that we need them most.The players are fine, theyre fully recovered. Of course the disappointment has been hard to swallow, but theyre professionals. Theres still a lot to look forward to. Not many teams can say that they have won the league and cup double two years in a row. Lionel Messi was largely on the periphery as Barca lost to Atletico Madrid in the Champions League Theres a world ahead of us - six league games. We need to perform well, avoid making mistakes, be effective and play good football. This is not our best spell of the season, and we just have to accept that.Aside from recent injuries to Rafinha, Jeremy Mathieu and Thomas Vermaelen, Enrique can choose from a full squad. Luis Enrique took full responsibility for Barcelonas Champions League defeat Meanwhile, Valencia are coming off an impressive 2-1 victory over Sevilla and head coach Pako Ayestaran believes his side have an opportunity against Sundays opponents.ddddddddddddell try to make sure that their possession is not so high, but we know that we will spend a long time without the ball and we have to know how to manage those moments, he said. Heres how Barcelona lost against Real Sociedad last time out in La Liga It is an opportunity, not a risk. The mental factor always has an influence. With Barcelona it is always tough, but it is important that we continue to grow from the line we have marked out for ourselves.There are aspects that you adapt depending on the opposition, but we are clear about the team are going and where we are growing.
