That howler by Ederson has woken a few people up at the Etihad.... it didn't stop him charging out of his area again just now, with his clearance (this time) bringing huge cheers from the home fans.

At the other end, City striker Gabriel Jesus is having a much quieter time, with only two touches in the first 15 minutes - the fewest of any player on the pitch.

Spurs have responded well and they are into their rhythm. They have had more possession and they looking for the equaliser.

Tottenham are all over the place at the back.

Daniel Podence runs through into the box but Davinson Sanchez chases him back, getting an-all important block from six yards out.

Earlier in the game, the ball was played into the same area and I expected Ederson to go out to it but he didn't. I just wonder if he is not quite right because he is usually so good with his feet.

Where's Ederson going???

A long punt from Shakhtar into the Manchester City half and the home goalkeeper comes steaming way off his line but misses his kick.

It allows Mateus Tete to charge into the box unchallenged from the right-hand side, but then sees his low shot blocked on the line by Fernandinho's slide.

A Shakhtar player was free, why didn't Tete pass it?!

Tottenham have fallen behind and threaten for the first time as Son Heung-min flicks on Harry Winks's header but Olympiakos goalkeeper Jose Sa makes a stunning, full stretch stop low to his left.

Kevin de Bruyne is finding that pocket in the number 10 position and he has picked it up five or six times. You just know he is going to have a major impact in this game.

You saw it coming, Olympiakos have had a great start.

Paulo Gazzaniga made the first save but they didn't learn their lesson and no one got out to close him down quick enough. The warning signs were there for Spurs.

Olympiakos deserve the lead. They have been right in to Spurs and the goal had been coming.

It's all Olympiakos at the Tottenham Hotspur Stadium in the opening five minutes.

Has Jose brought his bus?

Olympiakos' skipper tonight is Omar Elabdellaoui, who had a loan spell at Hull under Marco Silva.

Olympiakos have made a decent start in the capital.

Giorgos Masouras stings the palms of Spurs goalkeeper Paulo Gazzaniga with a rising drive from the edge of the box.

Banks of photographers to greet Jose Mourinho but nothing in the way of an official introduction to the crowd - in fact all very low-key.

Manchester City would love to get a couple of early goals so they can take their foot off the gas and get ready for the weekend.
