Totthenham will really suffer against Aston Villa because there is a little worry of injury crisis at Totthenham,and because of that,they will really find it difficult to win,meanwhile Aston Villa will have to tighten up their bet if they are to get any reasonable results against Totthenham.Despite the fact that Totthenham have some key players out due to injury,they still have a way of winning games,They still have some players who can cause problem to the Aston villa defence,Someone like Son is still available to play and he still has that chance of scoring goals thesame way he used to.But just that Maddison has really been someone who revived his goalscoring form.
Aston villa is an average team that hasn't done so bad or really good for themselves this season. In their last five games, they have lost only one, their performance when compared to Tottenham from the start of the season, Tottenham has a better strength except for now that they have got injuries.
Tottenham still gat the home advantage as they will be playing from home against Aston villa, they are right under the spurs on the standings. Tottenham regardless of the injuries is still a strong team that can't be under estimated yet , like you rightly said Aston villa would have to Play better if they must be able to win the Spurs at their home, because with player's like some and Madison who will be present, villas defense will be threatened, the player's who have been absent due to red card will be back so the spurs will once again be a bit though.
