Manchester United manager Ole Gunnar Solskjaer believes football is a "different game" this season due to the new handball rule.

Debate has raged over changes to the handball rule which have seen several penalties awarded, with United falling victim against Crystal Palace under a fortnight ago.

"I think football has changed," the United boss said. "There are no fans, it's a different game. Pre-season we were at different stages, the new handball rule... you never know what's going to happen.

"You can discuss it all day long but we need some clarity on what's a foul and what's a penalty because now it looks like you can chip the ball up into someone's hand - like what happened to us against Palace for example and Victor got a penalty against him.

"And then the header against Tottenham, he's [Eric Dier] got no idea the ball hits him. You see the goals scored against West Brom at the end, is that not handball [by Kai Havertz in the build-up]? We need to get that clarity. It's a whole spectrum of things that aren't normal."
