Lejeune will be reunited with former Magpies teammate Joselu, who arrived at the Mendizorrotza Stadium last summer, as well as manager Pablo Machín, who coached him during his time at Girona during the 2014/15 season.

Lejeune has made 44 appearance for Newcastle United since joining from Eibar in summer 2017, scoring twice – with both goals coming in stoppage time during a dramatic 2-2 draw at Everton in January 2020.
