Who plays, where and what formation is secondary. What MT first needs to sort out is to stop playing football like 5 years olds, where everyone moves towards the ball. Spread out! Move away from the ball and give players space.

Half the time we lose the ball or don't have anyone to pass to is because we crowd ourselves out. You can throw a blanket over half the team they are that close to each other. Do you expect Chieo to dance between 4 players in close proximity. At least two of them are only near him because they are marking two of our players who are also within 5 yards of him.
And then you wonder why there is no one in the box. When there are more players nearer the corner flag then the box there is something wrong.
