The agent of Palmeiras defender Yerry Mina says a pre-contract agreement with Barcelona is watertight.

It emerged yesterday that Mina is also attracting interest from AC Milan and Bayern Munich.

Mina's agent and uncle, Jair Mina, revealed: "We have signed a pre-contract and there is a chance that the boy arrives in Barcelona.

"It's true, however, that other European teams are interested."

The Colombia defender could join Barca in January after the Brazilian season concludes.
