Pau Torres
The Villarreal centre-half does have a pretty low release clause, at €50m (£46m), and with the defender still only 23 years of age, he is one for the future.
Torres is being pursued by the likes of Barcelona, Arsenal and Manchester City, but he has had just one season in Spain’s top flight, and Lampard may feel he needs someone who can come in to be a leader at the back.
