This is probably why I shouldn't say exactly what another poster meant, haha. At least in regards to the availability. I think the main point still stands, the slump period wasn't mostly trying to replace a 20 goal striker.
The funny thing is, by lining up the games he missed under Dome and the games NYCFC played during his absence, NYCFC went 4 wins, 2 losses, and 1 draw and scored 13 goals (1.857 ppg and 1.857 goals per game).
And actually, David Villa played more minutes under Dome Torrent in 2018 (1,131 minutes) than Patrick Vieira (880 minutes).
