Chelsea are also planning to intervene and make an offer for Mbappe according to some sources. Technically Al-Hilal have a way bigger potential offer for Mbappe. They are planning to offer 200 million euros for his transfer fee and 400 million euros per year for his contract also. This is like a dream offer for any player for sure.

However I don't expect Mbappe to accept any offer outside Europe at least for now. Therefore Chelsea should be comfortable about that. They had better meet PSG and Mbappe's demands both firstly. After that they will most probably have to fight against Real Madrid. I don't think Mbappe would prefer Chelsea to Real Madrid.
