Mount wasn't an EtH signing at all.
According to the Athletic, EtH originally wanted FDJ with Rice as the alternative (and that summer Rice was interested), but the club went for Casemiro. The following year EtH wanted Rice again but we were too late to the table and Rice went elsewhere, so the club signed Mount.
It also claims EtH wanted Gakpo (to solve our striker shortage) and Antony (to solve our RW shortage after Sancho said he wanted to play LW), but the club said he could only have one - this is of course after the club failed to sign both Martinez and Antony for £100M. We ended up over spending on Antony at the end of the window and loaning Weghorst in Jan. EtH then wanted Kane but got Hojlund.

It's interesting until recently most laid the blame of our signings at EtH door, but the reality appears to be quiet different.
