The lively loanee from Reading was heavily involved in the Millers impressive first half against Crawley, missing a guilt edged chance but then moments later netting the opener with a cheeky lob.
And after returning to the club for a second time after his first spell was cut short due to injury, the striker had a few mixed feelings after the 2-1 defeat.
"I`m not sure that we really picked up from conceding the equalising goal although we had a few chances in the second half and I think we were a little unlucky," he told Millersplayer.
"I`m happy with the goal and I could have scored another one as well but I`m gutted about the result. I think every player needs a run of games to get their form up. Bradford was my first game coming back to fitness from the injury and I`ve had a good run out today, it's good playing up alongside Revs (Alex Revell) so hopefully I can carry it on and get more goals."
Brett added: "When I first came here my target was to get double figures but the injury was a bit of a knock back so anywhere around seven or eight goals will be good. I just enjoy putting in a shift and a team performance."
