Craig Gordon is hesitant as Mitchell Dijks gets his head to a deep cross and the ball comes off the inside of the post. The Celtic goalkeeper redeems himself by clawing the loose ball away as a cluster of players throw themselves at it. A narrow escape for the visitors...

Ajax really should be level as Davy Klaassen rises to meet the ball in a central position maybe 10 yards out but he skews and awkward header narrowly wide.

Ten-man Celtic also make a change and it's James Forrest who is sacrificed for Tyler Blackett, who will fill in for the prematurely departed Emilio Izaguirre.

Ajax swap a Dane for Dane as goalscorer Viktor Fischer is replaced by Lasse Schone, who scored in each of the 2013 meetings with Celtic.

A now Emilio Izaguirre is off! What was the full-back thinking of as he chopped the legs away from Anwar El Ghazi?

Celtic pair Emilio Izguirre and Stefan Johansen, both on yellow cards, clatter into opponents in quick succession, drawing weak claims for further action from the home side.

Celtic are forced into a change as Mikael Lustig limps off and Efe Ambrose comes on to take over at right-back. The big Nigerian is involved right away as his uncertain touch forces Craig Gordon to look lively and come running to smother.

Upset-o-clock in Group A's other match: Molde are now 3-1 up at Fenerbahce, with Martin Linnes scoring on 64 minutes.

Celtic spring another counter-attack and Stefan Johansen cuts in from the right to try and find Kris Commons at the near post bit the pass is cut out by Thulani Serero. Leigh Griffiths then has a pop from distance, with Jasper Cillessen holding on to the skidding ball.

Ajax make a couple of changes, with Daley Sinkgraven and Amin Younes making way for Thulani Serero and Arkadiusz Milik.

John Everyman on Twitter: "In my view, Commons & Forrest are the 2 best players on the team & should be on the pitch in all but the rare circumstance #bbcscotfootball"

Kris Commons chips a cute ball over the top of the Ajax defence for Leigh Griffiths to run on to. The angle is tight and the striker is stretching as he volleys into the side-netting.

"Kris Commons underlying the madness of the decision to leave him on the bench at Aberdeen on Saturday. Two assists so far and every time he stands over a corner Ajax gulp hard. His deliveries are causing the home team huge trouble."

Celtic defender Mikael Lustig gets his head to another Kris Commons corner but can only steer the ball wide. The home fans are growing more and more disgruntled.

Molde take the lead against Fenerbahce again, with Mohammed Elyounoussi on target. It's 2-1 to the Norwegians now.

Celtic cause more problems from a Kris Commons corner, with James Forrest having two shots blocked in the area.

A few holes appear in the Celtic defence but the visitors are let off the hook as Davy Klaassen attempts a fancy flick when he had time and space to let fly with a shot from the edge of the box.

The impressive Amsterdam ArenA is close to full but the home fans have been pretty quiet. Can Celtic keep it that way?

Ajax exert some pressure and win a corner in unusual circumstances as goalkeeper Craig Gordon clips the heels of team-mate Emilio Izaguirre as he shapes to kick clear. The set-piece comes to nothing, sparing the Celtic duo any further embarrassment.

The second half is up and running. No changes in personnel for either side.
