Real Sociedad’s Inigo Martinez is Inter’s first alternative to Issa Diop, according to Premium Sport. The Spanish central defender is contracted through to 2021 and has a release clause of €30 million.
Inter are not alone in courting the 26 year old and face competition from rivals Juventus. Despite the Bianconeri being present, Inter are understood to hold the lead in the race for him, even though he is not their primary objective. Each side would be willing to pay his clause outright but Inter may attempt to negotiate and get him cheaper.

What about Carlos Vela?
last time i checked vela plays on the other end of the field
I know… I’m Mexican and I follow him and Real Sociesad closely. I suggested him as an alternative in our front, he is very very good and underrated, he could come cheap. As for Iñigo Martinez he was followed by Barcelona and other a few seasons ago but he has been inconsistent ever since.
