Honestly Tottenham or Manchester United have a higher chance of making the top four spot than Arsenal and Westham United. They have a bigger squad to adjust to the pressure that would come with the second phase of the league. Tottenham let go of some of their players who were not having much game time, like Tanguy Ndombele, Lo Celso, Dele Alli and Bryan Gil. They knew that these players will leave and they needed some replacement to booster their squad amidst their challenge for the top four, they got some players like Bentacur and Kulesevski. Arsenal just lost out about 6-7 of their players and refused to sign. How will they be able to cope when this fatigue and injury set in on the first team players. I don't see them even making the top 6.
What arsenal did sounds funny but I think they know better, maybe the have a better plan which no one knows about, just maybe. And talking about Tottenham I think they have a better chance of ending top 4 ahead of Manchester United and this is because they show more seriousness and commitment when they play unlike Manchester United who looks clueless during match day, they can’t seem to be in possession for long and the team isn’t even productive. Ever since the arrival of Conte Tottenham have been seen as a major threat and I feel that is how it should be and if they continue as they have been recently and with more sacrifices they can achieve what they are aiming for.
