ZALUSKA (6) In the team in place of Fraser Forster and wasn't at fault for any of the three goals.
MATTHEWS (5) Had difficulty dealing with St Mirren's Esmael Goncalves and Steven Thompson when he ventured out wide and didn't manage to get forward and deliver any telling crosses.
WILSON (5) Not commanding enough in the air. Both himself and Mulgrew lost too many aerial duals on the day and his passing wasn't always crisp enough.
MULGREW (5) Missed a penalty that denied his team the chance to take the lead and gifted St Mirren one at the other end to allow them to move into the lead. Scored a consolation goal.
IZAGUIRRE (4) Unless he can find the form he displayed when he first arrived in Scotland, you'd imagine his days at Parkhead are numbered. Poor defensively.
WANYAMA (4) As poor a performance as he has delivered in a Celtic shirt. Didn't boss the midfield and was second best to just about every second ball.
LEDLEY (5) Not the worst in the Celtic team but that counted for little when so many of Neil Lennon's men failed to turn up.
BROWN (5) Another who accepted second best throughout. Played most of the match wide on the right and didn't ask any question of the Saints defence.
SAMARAS (4) A disgraceful performance and looked very much like Samaras of old; lazy and disinterested.
LASSAD (4) Could pretty much copy and paste the same as for Samaras. Posted missing before being hooked.
HOOPER (5) Hit the bar with a first-half effort before levelling the scoreline from close range.
COMMONS (4) The damage was done before he arrived on the scene as St Mirren moved into a 3-1 lead as he waited to come on. Looked more dangerous in the short time he was on than anyone who started.
LUSTIG (3) A late replacement but he didn't influence the game.
STOKES (3) Showed a willingness to at least create something which was a lot more than most in the team.
