Michael Olise transfer update: Chelsea have a 'secret weapon' in their pursuit of the winger

Chelsea are in pole position to sign Michael Olise from Crystal Palace this summer, and they may have been given a transfer advantage over Manchester City thanks to a potential "secret weapon."

Chelsea have already made a verbal offer of €30 million (£25.9 million) for Olise, but Palace are expected to reject that bid unless it is increased to their £35 million release clause.

However, Chelsea may be able to soften the blow of losing Olise by offering Palace Lewis Hall on loan. Hall is a versatile left-back who can also play in midfield, and he is someone that Palace have been interested in signing.

The relationship between the two clubs is slightly soured after Chelsea's approach for Olise, but sending Hall to Palace on loan could help to mend fences. It would also give Palace a great option at full-back and in midfield, which could make them more willing to accept a lower fee for Olise.

Olise is a highly-rated young player who would be a great addition to either Chelsea or City. He is a creative winger with a lot of potential, and he would add another dimension to either team's attack.

It will be interesting to see how the transfer saga plays out, but Chelsea seem to be in the driving seat. They have a "secret weapon" in Hall, and they are willing to meet Palace's asking price for Olise.

It is likely that Olise will end up moving to Chelsea this summer, but Palace may be able to get Hall on loan in return. This would be a good deal for both clubs, and it would help to keep the relationship between them positive.
