The Brazilian has emerged as a key player for Unai Emery\'s side this season, linking with Soldado to good effect, and he will need to be both scorer and provider if Valencia are to get the goals they need to progress. The on-loan Chelsea shot-stopper is likely to come under severe pressure as his side hold onto their advantage, and he will be required to be at his very best in order to emerge with a positive result. Valencia\'s home record in Europe is far better than their domestic displays, while Simeone\'s side do not travel well. Los Che should win, but whether they can keep a clean sheet will be vital to deciding the outcome of this contest.
