Absolutely.
My recollection of last season, was we would quite often, sit back too much, once we had taken the lead.
Quite possibly a by-product of not scoring enough goals, but it often led to letting teams back into games we were in command of.
We had been defensively sound all season, apart from when defending a lead it seems.
No reason to suspect sitting deeper would make us more effective defensively,
Far better to continue controlling the game than cede the initiative to the opponents.
It's also notable that both our goals came from centres quickly fizzed in. Too often we've tended to stop, fanny around and pass it back. Moder and Mac Allister brought some speed and directness to the party. I wouldn't mind trying those two in a front three with Maupay in a 3-4-3, with Bissouma and one of Mwepu, Lallana, Alzate or Gross in midfield behind them.
