Arsenal right-back Hector Bellerin is close to a loan move to Spanish side Real Betis and Reiss Nelson has completed a season-long loan move to Dutch side Feyenoord.
Spain international Bellerin, 26, is scheduled for a medical in London later on Tuesday.
He has yet to feature for the club in this campaign and has two years left on his current contract.
Winger Nelson, 21, has played 48 times for Arsenal, scoring four goals.
The England Under-21 international spent 2018-19 on loan at Hoffenheim in Germany.
"I'm looking forward to playing in this beautiful stadium," said Nelson.
