Spurs might win today as they are a great squad overall and having a good season so far and United don't deserve to be on 4th place in my opinion and Spurs has the chance to push United on 5th position.
Chelsea...hard to say anything positive about them in the last 3 months so because of this reason , I don't expect much from this game or a victory of Chelsea.
Tottenham should be able to win against Aston Villa. After all, Tottenham is the better team going into this match. And if they win, they will be able to get ahead to the fourth position but they will have to wait for the result of the Manchester United match. Because if Manchester United wins also in the next match, Manchester United is going to go to that fourth position again.
And let’s not forget Manchester United has improved their performance recently. Actually, Manchester United is performing better compared to Tottenham. Manchester United should be able to win the next match because they will face a rather wicker opponent in the next match.
