Aston Villa manager Unai Emery says his team "believe in Villa Park" and the potential for home comforts to energise them, but can the Premier League side really stage a comeback to reach the Champions League semi-finals?
Paris St-Germain hold a two-goal lead at the halfway stage of their quarter-final tie against Villa after a convincing 3-1 win in France.
The French champions will be heavy favourites to progress to the last four when the two meet again in Birmingham next Tuesday night (20:00 BST).
But Villa are unbeaten in front of their own fans this season in the Champions League - even recording a home league phase win over six-time winners Bayern Munich.
