Having one striker and Adebayor not being an option is better than having two if last season's Ade is one of them.
We used no DM last year. We played Mason and Bentaleb. We still have them. Obviously, if we still have them, and Dier is being preferred ahead of one of them, that must be seen by the management as an improvement. Not even a halfwit would think one DM is worse than none, if what said halfwit wants is DMs. Capoue and Stambouli don't count, since they were shite and barely played.
We have added a highly rated CB, a good RB, an exciting quick prospect AM/striker, an AM who have performed brilliantly in Bundesliga and a promising CB cover. And we've got the exciting Pritchard back from his loan spell.
Meanwhile we didn't lose anyone that most people didn't want to get rid of, and rid ourselves of lots of disrupting elements who barely played and who didn't do well when they did play.
Improvement.
One would have to try hard to disagree.
