Milan Skriniar
Reports in Italy suggest the 25-year-old could be available for below €65m (£59m). He was subject to a bid from Manchester City for the same figure last summer, but the Slovakian has struggled for form somewhat this season.
Even so, Skriniar is equally comfortable playing in a back four or a back three and, considering Lampard’s tendency to switch systems, having someone as adaptable as the Inter Milan defender could be ideal.
