The best Chelsea cam do is park the bus if they try going head to head with PSG they'll get dominated in all areas thereby creating space for PSG to attack better and score. They shouldn't even allow PSG score first cause it would weaken them just like it happened to Madrid, Bayern, Inter and Atletico Madrid. Parking the bus is the best approach so they'll get a possible counter and score first. On a second thought I see everyone hyping PSG what if Chelsea happen to win with ease?
It could happen in a football match because a team will definitely have ups and downs that will happen and it will continue, of course Chelsea has fixed it with a strategy that has been arranged and PSG also applies many strategies that are difficult for their opponents to predict, especially regarding the many quality players and that is a strong support for their team, even though many teams conceded the first goal, at least they were able to equalize or reply.
Yes, in football, anything can happen. Indeed, PSG is currently the greatest team in Europe and this tournament, as evidenced by their crushing victories over other great teams like Bayern Munich, Madrid, and Atletico. PSG has even been called like Barcelona under Guardiola, with Messi, Xavi, and Ines being tough to beat, but the ball is round. Furthermore, Chelsea were underdogs when they won the UCL trophy, but Chelsea managed to pull off a surprise.
So, even though Chelsea are underdogs in this final, they still have an equal chance as PSG. Small mistakes by either team will decide this match. Chelsea have two new strikers who are eager to prove themselves: Joao Pedro and Liam Delap. I think one of them will score, and PSG will too. So, this match is unlikely to end 0-0. There will certainly be plenty of goals, so betting on the top scorer might be a wise choice.
