Florian Lejeune is currently undergoing his Newcastle United medical, Sky sources understand.
The French centre-back arrived on Tyneside on Monday after Newcastle reached an agreement over the structure of his £8.7m move from Spanish club Eibar.
Newcastle posted a suggestive tweet on Monday evening, showing a blurred image of a player being interviewed with the caption "Goodnight from the training ground... See you bright and early!"
Lejeune, formerly of Man City, will become Rafa Benitez's second signing of the summer, following Christian Atsu's £6.2m move from Chelsea, and the transfer should be sealed by Tuesday.
Newcastle had been locked in negotiations with the La Liga side Eibar for their French centre-back for a number of weeks.
Talks progressed slowly over the past month with Eibar wanting the player's £8.7m release clause paid up front rather than in instalments but Sky Sports News HQ understands the two clubs have settled a number of differences over the weekend.
The 26-year-old played a key role for Eibar last season, helping them finish 10th in La Liga.
Paris-born Lejeune is a former France U20 international. In 2015, he signed for Manchester City but was immediately loaned back to the Spanish second tier side, Girona, before moving on to Eibar last year.
