He did come in from the side and his arm was going up to meet gross neck (not head )actually , your manager blaming the weather was far much funnier , think that BHA should ask Webb for the VAR HQ recording of the incident ....From the repeated replays on MOTD, it looked as though as Palhiñha came in from the side, his arm was going up to balance himself and simultaneously Groß's head was coming down. From some angles (Inc, presumably the ref, lino, your players and VARs) didn't think it was a foul at the time. Admittedly the angle retweeted constantly on Twitter by some of your fans does make it look bad.
