The blues will be hoping that this season will be the one that sees them claim the trophy for the first time, but face a difficult opening challenge against the team currently lying in second place in the Portuguese Primiera League.
Porto have an identical opening record to City, having won two, drawn one and lost one of their opening four matches and have seven points. They currently trail leaders Benfica by five points. Last time out, Porto salvaged a 2-2 draw with Sporting. After leading from the 9th minute, Porto found themselves 2-1 down at half time and needed a goal three minutes from time to rescue a point.
The visitors have won the competition twice. The first time was the 1986/87 season when it was known as the European Cup, before Jose Mourinho guided them to the trophy in the 2003/04 season.
Alex Telles is the big threat to City. From the three games played, Telles has had six shots on target, scoring two but also creating two for teammates, and his shot accuracy currently stands at 83%, the third highest in the league.
Despite Telles providing the most assists, Otavio will be a threat to the blues. The attacking midfielder has a pass rate of 80%, with 160 of his 199 passes being successful, although it needs highlighting that the 39 incomplete passes are the highest in the Primiera League.
City and Porto have faced off in just one European tie. That came in February 2012 in the Europa League. The blues won 2-1 in Portugal before thrashing the visitors 4-0 two weeks later, and blues fans will be hoping for a similar result tomorrow,
