Five key battles for Porto’s Champions League clash with Chelsea

Pereira is far from the tallest at 5ft 8in, but a low centre of gravity might actually help him handle Hazard, whose infield incursions just haven’t been as effective lately. They say form is temporary and class permanent, though, and so Hazard holds a 7/4 anytime scorer price.

Giannelli Imbula v Cesc Fabregas
Defensive midfielder Imbula has a big €20m price tag to live up to after joining from Marseille this summer, so can press his claims for a full France call-up by marking Chelsea playmaker Fabregas here.

Porto also have their own box-to-box man in the engine room with Hector Herrera, and he’ll have to curb his natural enthusiasm when the visitors are in possession to stop space appearing in behind.

Spain’s Fabregas rounded off the Blues’ 4-0 victory over Maccabi Tel Aviv last time out in Eruope, and is 7/2 to net again anytime here.

Julen Lopetegui has a selection dilemma in his wide berths, because late summer signing Corona has scored three in as many league outings for the Dragons.

There isn’t room to field him, Algeria star Yacine Brahimi and Barcelona loanee Cristian Tello, however, but we fancy the Mexican to get the nod.

Chelsea defender Azpilicueta, meanwhile, has competition of his own to worry about now in the form of Ghana full back Abdul Baba Rahman. Corona’s purple patch is 6/4 to continue with a goal anytime, whatever part he plays.

Resting him by starting the Cameroon international on the bench this weekend, striker Aboubakar will want to use this opportunity to show everybody he can fill Jackson Martinez’s shows for Porto.

With six goals in seven games this term so far he will pose a definite threat, even for man mountain Zouma. Aboubakar, 11/2 to score last, has got the better of the Blues’ great defensive hope before, when they lined up for Lorient and St-Etienne respectively.
