With a record of the results of Arsenal match against Tottenham must draw or lose, but i doubt that will happen, my prediction is that Arsenal will win in this match, so Arsenal will remain in position 2 of the standings.
I'm beginning to feel bad for Tottenham Spurs and their manager; they've lost four games in a row, but they'll face Liverpool in the Carabao Cup and Arsenal in their next Premier League game. I am confident that they will lose both matches since they are not at the same level as their opponents. If care is not taken, Tottenham's management could fire Postecoglou and bring in a new manager because their current performance will not get them anywhere this season.
Honestly, the only thing Tottenham Spurs can do at the moment is to finish the remaining matches as much as possible, it is true that in the last four matches they have lost three and won only one and that too against Southampton, we all know it is a very weak club. In the match against Arsenal later despite losing i hope there is no massacre, at least if Tottenham manages to finish the match with a smaller goal difference, that's better.
