Everton are close to agreeing a deal with Valencia for centre-half Aymen Abdennour, according to the Mirror.
Ronald Koeman is said to be ready to continue his summer spending on an offer of £14.5million, plus add-ons.
The Tunisia international joined Valencia from Monaco last summer for £17m.
The Goodison Park club are lining up alternatives with Sunderland boss David Moyes yet to agree to sell Lamine Kone.
Valencia owner Peter Lim was in London at the weekend to discuss the potential sale of Abdennour, as well as that of Shkodran Mustafi to Arsenal.
