Callum McGregor forces a fine save from Motherwell goalkeeper Dan Twardzik, especially as the shot took a wicked deflection. McGregor follows it up with a drive that finds the side netting.

Motherwell midfielder Iain Vigurs is booked for complaining about not being given a foul.

Callum McGregor fires a shot just wide as Celtic find renewed confidence and almost go ahead immediately after their equaliser. It could be a long last 20 minutes for Motherwell.

Celtic captain Scott Brown looks as surprised as anyone as referee Brian Colvin points to the penalty spot. Craig Reid's challenge looked to be outside the box and the home midfielder stumbles into the penalty box.

No matter, Kris Commons is not complaining as he slots away the spot kick.

"The difference between this and the first half is that Celtic are moving it quicker and it is backs to the wall now for Motherwell."

"Celtic have not been great after the break, but you can certainly see there's a bit more about the team after those two substitutions."

Callum McGregor cuts inside before curling a left-foot drive towards goal, but the midfielder is thwarted by a fine save from goalkeeper Dan Twardzik.

You could be forgiven for forgetting that John Guidetti was on the park, but the on-loan Manchester City striker bursts into life to pounce on an Emilio Izaguirre cross but finds the side netting.

Excellent play by substitute Kris Commons wins a corner for Celtic and, following his own corner, the midfielder fires a drive that is well held by goalkeeper Dan Twardzik.

"It's the second time in matter of weeks that Ronny Deila has not been scared to use his squad players, but it could be the second time it costs them points.

"Motherwell have looked solid enough, with Dan Twardzik only having two real saves of note, both from defender Jason Denayer.

"At the other end, John Sutton will feel he should have had a second, while, if Keith Lasley had been a bit quicker at getting the ball out from under his feet, he too could have been on the score-sheet."

"Stuart McCall will be delighted with his players but will be fizzing that John Sutton missed that chance to put them 2-0 ahead."

Ronny Deila has only managed five wins in 12 matches as Celtic manager and that unimpressive record will become worse unless he can revitalise his much-changed side during the half-time break.

Celtic defender Virgil van Dijk sends an effort against the upright following a corner in the first real danger to Motherwell's goal.
