The 10 men of Celtic failed to hold onto a two-goal lead as they drew 2-2 with Bologna in the Europa League.

Reo Hatate scored before being sent off for two bookable offences in the first half, and Auston Trusty's subsequent goal did not give Celtic enough breathing room as Thijs Dallinga and Jonathan Rowe scored in the second half to rescue a point for the hosts.

Bologna made the worst possible start when goalkeeper Lukasz Skorupski passed the ball straight to Daizen Maeda in the box, and the Celtic forward squared it to Hatate in the middle for a simple finish.

The hosts were then in the ascendancy, with Kasper Schmeichel making saves either side of a crucial block from Liam Scales, and their momentum seemed to be growing before Hatate received two yellow cards in the space of three minutes.

Trusty then scored completely against the run of play in the 40th minute, turning home from Arne Engels' flick-on to the back post, but Dallinga brought Bologna back within a goal with a header early in the second half.

Rowe then restored parity with 18 minutes to go after Schmeichel was left unsighted in a crowded box, and the ball went to the goalkeeper's right and into the back of the net.

Celtic were pinned in their own half from then on, but they did well to prevent Bologna from creating any big chances as both sides settled for a point at the Stadio Renato Dall'Ara.

Data Debrief: Mixed emotions for Celtic

Despite being a man down for the second half, O'Neill and Celtic would have hoped that they could hold onto their two-goal advantage. Instead, Bologna had 84.4% of possession after the break as they forced a comeback.

Overall, the Serie A outfit produced 2.34 expected goals (xG) from 34 shots to Celtic's 1.99 from eight attempts, with only two of those shots coming in the second half.

Schmeichel's seven saves will give the Bhoys some hope that they can still qualify for the play-offs, though they will need some other results to go their way.
