They have only 2 days to rest for the finale. It is 4 days for Betis. Chelsea players would be more tired. I think Betis will have more chance to catch them by surprise in the current situation. Do you think the same as me?
Tired you say? How else can you be more motivated to go into a major final than winning a major game that has landed you in the champions league you've longed anticipated to get to? Obviously fatigue and tiredness might set in but I can just be too certain of what the coach will tell his players. The team talk will be like, "you've come a long way to get to this point, you have just 90 minutes to give it all and then you can rest for as long as you wish to. How will you feel if you're able to qualify for both the champions league and still win the conference league without suffering any defeat? Go for it boys!!"
Regardless of the odds, if Chelsea can keep her heads up, they have all the psychological support they need that will give them a win in this game. Finals is about he feels they deserve it more and beating Nottingham forest is enough motivation to go into that game as though they've already won before the start of the game.
