Arsenal should put in all there efforts because they are in a dangerous period, any slight missup in Arsenal squad, then Arsenal is already in problem, Arsenal should really put all their efforts in the last matches remaining, they shouldn't underestimate any of those clubs, because a small club can fuck them up, I know Arsenal have really tried this season and they really deserve the Premier League, but they have to continue with the good performance till the end of the season, if they start misbehaving now, then Manchester city might overtake them, and all their efforts is wasted.
The Gunners have come this far with an outstanding form to lift the EPL trophy and I don't see them backing out on it no matter how pressured other teams make them feel, Man City are getting close but whenever I see that 8 gap I just say it's over in the chase for that 1st position for City.
In terms of worries, yes Arteta should be worried about some key players who went on international break and coming back with injury especially the man called Thomas Partey, if the injury is that serious then his replacement should be at high form to take his [Partey's] place because this isn't the time to say we lost due to missing players. Arsenal are almost there so no excuses, at least the up front are still in good shape with the return of Gabriel Jesus.
So with Arsenal going against Leeds I'm still going to say it that is a big win for the Gunners, as for City they have to battle it out with Liverpool, either they (City) shake hands and call it a draw or they lose all 3pt to Liverpool.
