Despite going on to win the game, it proved far from comfortable for the Americans at the Lanxess Arena in Cologne.

The Russians led after 12 minutes when Nikita Gusev scored his first of the match.

Within a minute of the start of the second period, the US were level through Kevin Hayes, but Russia were soon in front once more when Anton Belov scored.

Dylan Larkin restored parity at 2-2 before Gusev's second of the match put Russia in command once again.

Hayes' second pulled the US level before they were finally in front for the first time when Anders Lee scored midway through the third period.

The victory and top spot were then secured when Brock Nelson added a fifth for the Americans.

"It's a big win, it's pretty special to win and to come top of the pool," said Johnny Gaudreau of the US.

"It's one of the goals we set at the start of the tournament and play well in the medal rounds.

"It's a great win, I think we grew as a team today.

"It was a great effort."
