Manchester United carry a 1-0 lead into the second leg of their Champions League quarter-final against Chelsea at Old Trafford tomorrow. Here we look at the likely key battles.
Nemanja Vidic v Fernando Torres
United's defensive linchpin this season has infamously been tortured by Torres in the past. Current form would suggest the battle may go the other way this time but, as pressure continues to mount on Torres, there may be no better stage for him to score his first Chelsea goal.
Antonio Valencia v Ashley Cole
A potentially intriguing contest on one of the flanks. It will only be the fifth game of Valencia's comeback from a broken ankle but he has quickly found his form. The attacking threat of Cole is likely to be crucial for the Blues as they seek a way back into the tie.
Wayne Rooney v John Terry
Rooney returns for a game sandwiched between his two-match domestic ban. The striker could be asked to lead the line alone for United but will need to get the better of his England captain and proud Chelsea leader Terry.
