The bookmakers only provide odds @1.28 for Tottenham and this indeed low odds but with the current condition of Tottenham it's normal if the bookmakers placed them as the favourite especially Sheffield United conditions is not really good that until week 4 they still unable to gets the winning result and as we know Tottenham currently is very solid and their defense also impressive because from 4 matches Tottenham only conceded 4 goals
The losing of Kane make Son Heung-min can able to performing well again and it proven from his goals records that currently he has scores 3 goals and not impossible too in this match Son will be able to scored again and considering Sheffield United defensive lines which is quite weak so i expect Tottenham can win with big scores today
Sheffield United, a very weak team, is successful in the championship division, which is very different when they have to compete in the English Premier League, in four matches they only get 1 point, especially since they will face a team that has so far shown a good performance, so the two teams are in different conditions. It's normal for Tottenham to get very low odds, especially since this will be Tottenham's home match so it will give them more advantages.
When Tottenham played against one of the promoted teams they managed to score a lot of goals, and this is very likely to be repeated, Son Heung-min scored a goal even though it was no longer a hat trick.
Tottenham with their new coach are performing well, but when they start to meet strong teams, it will be a difficult match to face, maybe they will start to lose, but against Sheffield United, they will give Tottenham 3 points.
