Manchester United star Juan Mata believes Antonio Valencia will hold the key to a Champions League victory against CSKA Moscow on Wednesday.
The Ecuador winger scored the only goal of the game when United last visited the home of the current Russian Premier League leaders in the group stages of the 2009-10 season.
With Louis van Gaal's side having lost their opening away game against PSV last month, Mata hopes Valencia can offer some insight into inflicting a first home defeat on Leonid Slutsky's side this term to take them to six points from three games.
"We have three points after the first two weeks and the game in Moscow could be crucial," Mata wrote in his blog. "Defeating CSKA would give us momentum ahead of the last three games.
"I've been told that Antonio Valencia scored the winner for United the last time the team visited CSKA, so we will ask him for the secret to beat them because they haven't lost at home this season, both in the group stage and in the previous rounds."
For coach Leonid Slutsky, however, a lack of control during those two game is placing unnecessary pressure on CSKA's players.
"Unfortunately, we're unable to control the entire match at the moment," he said after the Ural win.
"Even those games, which went relatively well for us, like the game against PSV or today's game, we turn these games into victories by a single goal. The score puts some pressure on you in these situations."
