Crystal Palace attacker Michael Olise’s proposed move to Chelsea is unfolding amid a backdrop of ‘tapping-up’ concerns, Mail Sport understands.
France Under-21 international Olise is a target for the big-spending Blues, who are understood to have submitted an offer that activates a complex release clause, understood to be in the region of £35million, in the attacker’s contract.
However, Chelsea’s interest in the winger has aggravated Palace officials, who believe the Stamford Bridge club have crossed the line in their conduct during their attempts to sign the player.
Multiple sources have told Mail Sport that Palace have communicated their grievances in an unofficial capacity to their Chelsea counterparts.

Nevertheless, the west London club have continued their pursuit to the point where they have now tabled a formal bid that they believe activates his release clause.
There are concerns at Palace that Chelsea’s potential swoop for Olise has contravened transfer rules and etiquette.
Sources have indicated the south London club have considered formally reporting their top-flight rivals for making an illegal approach, though whether they are prepared to take such a drastic step remains to be seen.
