Arsenal are moving for Gremio defender Walter Kannemann.
Calciomercato.com says the Gunners are looking to the Argentinian international, 28, to solve their defensive problems.
Their report states the Europa League finalists are attempting to beat Serie A outfit Sampdoria to the centre-back by lodging a bid now.
And that £10.5m figure could rise if the ex-San Lorenzo and Atlas ace hits certain performance targets.
Kannemann is regarded as one of the best defenders in South America.
He has shone for Brazilian club Gremio since his arrival three years ago and played a key role in the Copa Libertadores success in 2017.
