Playing the Dons 2 days after Chelsea will be tough if we field most of the first teamers. We also then have Sheffield some days later. Our priority is to win our league games. We should have adequate strength to field some fringe players who aren't playing regularly.
e.g.
Adrian, Hoever, Gomez, Lovren, Larouci, Milner, Lallana, Naby/Ox, Brewster, Origi, Shaq with a few first teamers as subs if we really need them in the last 20 mins.
Apart from full back, there's still a lot of experience and senior pros playing there. We can afford to not risk a few first teamers a couple of days after Chelsea, especially against a team that will look to compete physically.
