The Colombian winger is being tracked closely by both Bayern Munich and Barcelona this summer, and now a key detail has come to light.

According to reports (via Spanish outlet Cadena SER), Diaz has a gentleman’s agreement with Liverpool.

With no signs of a contract extension and just two years left on his current deal, Liverpool faces a decision: hold firm, or cash in.

Diaz has reportedly rejected renewal talks so far.

And while the Reds insist he is not for sale, there’s growing belief that a high enough offer could change that stance.

Both Bayern and Barcelona are pushing hard.

Bayern are reportedly prepared to pay around €60 million up front (via BILD).

They hope to close the gap with performance bonuses, but Liverpool seems in no rush to budge.

Meanwhile, Barcelona are also said to be Diaz’s preferred choice.

The next few weeks will show if this is just smoke — or the spark that lights up the summer transfer window.
