Arsenal have scheduled medicals for Declan Rice and Jurrien Timber over the next 48 hours.
Rice is arriving for a British record 105m from West Ham and Timber from Ajax for near 40m.
The London Evening Standard says Rice's fee is for 100m up front plus 5m in bonuses. Timber will join for 34.2m up front, with a further 4.3m due to be paid in add-ons.
Arsenal have already splashed out 65m for Kai Havertz from Chelsea.
It means, Arsenal will have paid over 200m for three summer additions.
