It is very disappointing and a huge blow for Arsenal at a crucial moment like this when they have to go head to head against one of their worst rivals in the premier league. I am sure the opposition fans will be so excited about the recent development. I am hopeful Merino can fill in against Spurs because I hear he is back in training or we will see a pairing of Thomas Party and Jorginho in the weekend with Ethan Nwaneri starting against Spurs.
This is not very good because with Odegaard's injury then indirectly this is their 6th player who cannot play especially with Odegaard's condition now he could have rested for several weeks later.
This September does not seem to be a good month for Arsenal because they are in trouble where they are required to make a better performance in order to create an ideal competition instead they have to leave some of their core players.
Facing Tottenham this will not go easily for Arsenal because after all playing away coupled with the current condition of the players who are not in top condition, it will indeed be very difficult to get 3 points in this match.
