He made his Liverpool debut last week, coming on as sub when Liverpool were beating Man Utd 3-0 ... then United scored.
Last night he was 57min sub, and failed to find the net or set up a goal.
Kenny Dalglish's side lacked pace and creativity without injured captain Steven Gerrard and the ineligible livewire forward Luis Suarez, and Carroll could not turn things around after Brazilian Alan had converted a 17th-minute penalty.
Ten minutes after the restart Carroll was sent on for Christian Poulsen, with Spearing dropping back into central midfield and Meireles moving to the right.
His early involvement saw him head over Meireles' corner, although he was adjudged to have committed a foul in the act, and then had a shot deflected for a corner.
Carroll's arrival certainly livened things up, with Braga unable to handle his aerial power; Liverpool's problem was they were not proving him with decent enough crosses to threaten the hosts' goal.
Carroll continued to win headers with confident regularity but they were mostly in non-threatening positions from Reina's long punts up field, with absolutely no service coming from either flank with Cole cutting a particularly inconsequential figure.
