Even though the match result against Sheffield United will not affect Tottenham in any way even if they lose it but I think the Tottenham fans will surely not be happy if their team are unable to beat the bottom team of the table. I guess Tottenham will wrap up this season with a victory for their travelling fans in their final match tomorrow against Sheffield United.
Tottenham certainly cannot compete for 4th place with Aston Villa to attend the Champion League. However, they still have tickets to play in the Europa League, and this is something that Tottenham needs to hold onto at this time. It's quite a pity for them that they started this season very well but were unable to maintain their form in important stages of the season.
The match against Sheffield will be quite easy for them. Sheffield was relegated. Obviously, this is a good opportunity for Tottenham to ensure tickets to the Europa League next season. If they unfortunately draw with Sheffield, they will still have tickets. The victory is quite clear for Tottenham.
