article: Aston Villa take on Liverpool in their FA Cup semi-final encounter on Sunday with the competition both sides' last chance to win any silverware this season. Sportsmail columnist Jamie Redknapp looks ahead to the Wembley showdown and where the match could be won and lost with individual player duels. CHRISTIAN BENTEKE v MARTIN SKRTEL . This will be a heavyweight contest that could decide the game. Christian Benteke is superb in the air and Martin Skrtel will have his hands full. Liverpool have to stop the supply line because defending crosses has been their Achilles heel this season. Christian Benteke (centre) scored the only goal of the game as Villa won 1-0 at Tottenham on April 11 . Liverpool defender Martin Skrtel (right) will have his hands full trying to stop Benteke on Sunday afternoon . FABIAN DELPH v JORDAN HENDERSON . This should be a good contest between two England team-mates. Fabian Delph’s new deal was a real boost for Villa - he drives that midfield, though he doesn’t get enough goals. You used to say the same about Jordan Henderson but he has improved so much. England international Fabian Delph (left) and Jordan Henderson are set for a midfield battle at Wembley . RAHEEM STERLING v RON VLAAR and NATHAN BAKER . Ron Vlaar and Nathan Baker make an imposing back line but they would rather be up against a Benteke than a Raheem Sterling, who will float around and make himself difficult to mark so he can use his lightning pace to get in behind them. Raheem Sterling's (left) pace and trickery is bound to cause the Villa defence a lot of problems . Ron Vlaar (left) was part of the Villa defence that kept a clean sheet at Spurs in the Premier League . The Holland international and Nathan Baker (right) will be hoping to do likewise against the Reds at Wembley .
