Yup agreed 100%.
Only thing I want to add is that if this was a regular season with everyone fully fit, we would've played one of our existing attackers from the right (Rashford / Bruno / Eriksen). Only reason Elanga started is because a few players (Ronaldo, Sancho, Eriksen) aren't available / fully fit.
Elanga / Rashford isn't a great forward line either, esp when Bruno isn't at the top of his game. I think Elanga can be a backup to Rashford from the left because they're somewhat similar but not to Sancho on the right.
