Liverpool have rejected a deal worth £30m for Senegal forward Sadio Mane from Bayern Munich.
The Reds have been left bemused after the German club returned with the offer after an initial bid, reported to be worth up to £25m, was turned down.
Liverpool are understood to want about €50m (£42.8m) for 30-year-old Mane considering Bayern's similar valuation of 33-year-old Robert Lewandowski.
Mane and Lewandowski both have one year remaining on their current deals.
Poland international Lewandowski wants to move to Barcelona this summer after a decade with Bayern.
Mane has been more coy about his future.
