Wolverhampton Wanderers have completed the permanent signing of Jonny from Atletico Madrid after a successful loan spell.
The Spaniard has agreed a deal at Molineux until 2023, having spent the first half of the season on loan.
Jonny has made 20 Premier League appearances for Wolves, primarily at left wing-back, scoring one goal.
His performances earned him a first full Spanish call-up in the autumn.
He is Wolves’ third transfer of the January window after David Wang and Ed Francis.
Wolves are next in action at Everton on Saturday.
