Omnipresent at times. The Brazilian is showing the benefits of a sustained run of fitness and involvement, and he is revelling in United's mantra of one-touch pass-popping.
A slightly quieter afternoon for the England winger, as the majority of United's attacks came down Bolton's left flank, but nevertheless a solid display to prolong his fine start to life at the Reds.
Magnificent, once again. Three shots spawned three goals and a second successive hat-trick, and he is pulling all the strings in United's new-look attack.
Took only five minutes of his first start of the season to score, and looked absolutely lethal throughout. How his first hat-trick eluded him remains a mystery, but it will come sooner rather than later.
Michael Carrick (on for Tom Cleverley, 8 mins)
Thrown into the mix in difficult circumstances, but brought his trademark cool and calm to the United engine room and turned in a typically effective performance.
Ryan Giggs (on for Young, 68 mins)
Even when he comes on in an already one-sided game, Giggs has a galvanising impact. Wonderful pass to Nani in the build-up to Rooney's hat-trick strike.
Chris Smalling (on for Evans, 68 mins)
Rested after his England exertions, the hulking defender slotted seamlessly into the heart of defence against a Bolton side pushing for late consolation.
