Judging from both teams previous meetings, predicting the game won't be an easy one in all aspect. PSG played good game last season and are still maintaining such consistency in the club world cup now that's why it's difficult to write PSG off as club world cup winner this season,  the presence of there dangerous attack that have the ability to cut across all diffensive obstacles of any opponents and there aggressive defence makes them very difficult to lose the game. On the other hand, Chelsea maintained an unexpected consistency in the ongoing tournament and can still win the game tomorrow but it's difficult to conclude that they can win PSG tomorrow. All I know is the end shall justify
