I just checked the betting exchanges for the premier league games that will be played in this week, I am quite surprised with these two games.

The bookies are underestimating Spurs and Man Utd

yes I know they are poor in this competition and probably won't be going at full steam considering they have to prepare for the UEFA league final but still they are teams with quality squads, so is this an easy bet for the hosts?
What has been shown in the last match of Manchester United and Tottenham makes it very reasonable for the odds issued by the bookies for the match this weekend.
Manchester United and Tottenham will not play hard again because they are more preparing for the Europa League final match so Manchester United or Tottenham will not take risks in this match which will harm their squad for the final match later while Aston Villa and Chelsea are in dire need of points to secure their position to be able to get tickets to play in the Champion League next season so it is natural that Aston Villa and Chelsea are very favored in the match later.
