Chelsea winger Christian Atsu is having a medical at Newcastle ahead of a proposed season-long loan, according to Sky sources.
The 24-year-old is expected to finalise personal terms on Tuesday on an arrangement which includes an option to buy the Ghana international outright at the end of the loan spell.
Atsu signed for Chelsea in a £3.5m deal from Porto in 2013 but is yet to make a first-team appearance for the Blues.
The winger has been loaned out in each of his three seasons since signing a five-year contract at Stamford Bridge.
Atsu joined Chelsea's affiliate Vitesse Arnhem in 2013-14, Everton in 2014-15 and both Bournemouth and Malaga last season.
He has 42 caps for Ghana, where he began his career with Feyenoord Fetteh before joining Porto's academy in 2009.
Meanwhile, Newcastle midfielder Cheick Tiote, who has been pictured in Istanbul, is understood to be close to a move to Galatasaray.
