#4 Pedro (Chelsea)
It was needed for a former Barcelona man to be on the list, isn't it? So, Pedro is the name. The former Barca No.7 has flourished even better with Chelsea and would be certainly the man who'd test the Catalans' defence.
With Chelsea posing attacking threat through Zappacosta, Willian, Marcos Alonso and Hazard himself, Pedro is more likely to be not under Barcelona's defensive radar. His performance has helped Chelsea in the Premier League a lot of times but the Spaniard has been less influential when it came to European contests. But this time the forward can rise up against the odds in his first clash against his former team as he has many reasons to do so.
Chelsea's attacking spearhead,Hazard would need help from Pedro to amplify his presence against the La Liga side. It'd surely be worthy to watch this forward play against his ex-team in a crucial fixture which is to take place this midweek.
