Newcastle's record signing Miguel Almiron is expected to train with his team-mates for the first time on Wednesday afternoon after being awarded his work permit.
The 24-year-old Paraguay international, who completed a deadline-day move to St James' Park from Major League Soccer side Atlanta United, had to leave the country while the paperwork was completed but he is now back in the north east.
The playmaker is understood to have cost the Magpies in the region of £21m after a prolonged January pursuit which went close to the wire.
Almiron could get his chance when the Magpies visit high-flying Wolves on Monday evening, live on Sky Sports.
His capture represented a significant shift in a saga which has dogged the club in the last year or so, with owner Mike Ashley refusing to spend heavily in the transfer market while interested parties sought to put together workable takeover plans, and Benitez declining to sign a contract extension without assurances over the current regime's ambition.
