Could be.
Begs the question, though: Will he also be bringing in a starting No 10, or will he rely on whatever we have (Mickey, Mata) for that?
If it's the former, and the Perisic interest is genuine, we might look at:
Herrera.....Pogba
Mickey/Mata..........Mata/Mickey..........Perisic
Morata
Doesn't fill me with great confidence, to be honest.
I'd much rather see us unleash Pogba to a greater extent in a 4-3-3 variation, with an added DM of sufficient quality.
DM
Herrera......Pogba
Mickey..........Morata..........Martial
