The game is vital for both clubs in their battle to beat the drop.
â€śFirst of all we have to look after ourselves,â€ť said Cuellar to the Birmingham Mail. â€śWe need to win and carry on to the best finish possible.
â€śI hope we are going to win on Monday. Afterwards I wish Villa all the best to win their last three games.
â€śItâ€™s going to be strange, as it was when I played my first game against them earlier in the season.
â€śI am playing against friends with whom I trained and worked so hard for four years.
â€śIt will be emotional to play there, but I am ready for that and very excited."
