Following their 5-0 shellacking of Liverpool on Saturday, City are expected to start their campaign with a victory.
Guardiola coached Toure at Barcelona, where the former Ivory Coast global lost his place in the first XI and was transferred to City in 2010.
Feyenoord [8.80] have only claimed two wins in their past 15 Champions League outings (W2-D6-L7) but are making their first appearance at this level since 2002/03.
Readying themselves for a tough game against Manchester City on Wednesday night, Feyenoord know they'll have to play to the best of their abilities if they want to stop Pep Guardiola's attacking side.
"They make the pitch big, that is a quality of them and it is hard for the other teams".
Captain Vincent Kompany will miss out for City once more due to his latest calf injury setback. "It is between him and me, it's a sporting decision". Six players finished their contracts last season and Yaya is the only player who we decided could stay because he is a special player.
Eyes in particular will be on City playmaker Kevin De Bruyne, whose sublime form played a major part in the Liverpool drubbing and who is sure to sniff out and exploit weaknesses in Feyenoord's midfield and defence.
Ederson is with the squad despite having eight stitches in a facial wound after being caught in the face by Sadio Mane's boot at the weekend.
City defender John Stones praised the keeper's bravery, saying: "Ederson has got on with it straight away".
"When you're at a club like City, you have to do your best to win all the trophies you compete for", he told the club's official website. He wants to be around the team, in that environment. "We will see in the next weeks but I think it will be soon when he comes back and fights to play".
