The Independent says Arsenal have a £12 million agreement with Shakhtar for Jadson.
Few will see Jadson as a like-for-like replacement for Cesc Fabregas, despite his physical similarities to the Spaniard, and at 27 he is not the next big thing in Brazil.
But Jadson arrives with the advantage of being ready to launch straight into the season, having been heavily involved in the Ukrainian campaign, which is well under way.
He said yesterday: "If everything goes to plan, I'll have some news for everyone at the start of next week. Hope it works out."
