Millwall have signed Arsenal right-back Brooke Norton-Cuffy.
Norton-Cuffy joins Millwall on-loan for the season. He spent last term with Rotherham and Coventry City.
"We are delighted to welcome Brooke to the club," said Alex Aldridge, Millwall's Director of Football Operations and Recruitment.
"He is held in very high regard by Arsenal - both as a player and as a character - and he has exciting attributes that we feel can really strengthen Gary's squad.
"Brooke joins us after a year of playing in The Championship over two loan spells last season, as well as in important Play-Off games for Coventry, and those experiences will no doubt stand him in good stead to make a positive impact in a Millwall shirt."
