Luckily for Watford, Dennis is no longer going to the AFCON. A big plus for them if you ask me.

For Arsenal I think they will fare well without those players whom, if you look critically have become "fringe" members of the squad and they have players who can readily fill their voids.

Auba has been frozen out - Nketiah and even Balogun for cup games, that's if they don't bring in another striker. Martinelli has also always shown interest in playing centrally.

Pepe has been almost non-existent, save for the last cup game.
And for Elnenny who isn't a first team player, they have Lokonga and even Maitland Niles. I just feel the depth at Arsenal is enough.
