Celtic drew 3-3 with Manchester City in a thrilling Champions League Group C game at Parkhead on Wednesday night.
In an incredible first half, Moussa Dembele gave Brendan Rodgers' side a third-minute lead but Fernandinho equalised for Pep Guardiola's men.
Celtic were hugely impressive and were back in front in 20 minutes when Raheem Sterling turned a Kieran Tierney shot into his own net but Sterling hauled City level with a cool finish before half an hour had been played.
The Scottish champions went ahead for the third time with a spectacular overhead effort from Dembele just after the break but the Premier League leaders, with a 100% record before tonight, again rallied and Nolito beat Craig Gordon in 55 minutes.
It finished all square after a breathless 90 minutes in Glasgow while Barcelona hit back to beat Celtic's next opponents Borussia Monchengladbach 2-1 in Germany.
