Brannagan, 19, made his debut for the club against Bordeaux in the Europa League.
Teixeira, 22, spent last season on loan to Brighton in the Championship – where he won their player of the year. He’ll be making his full debut 623 days after making his debut as a sub at Fulham in February 2014.
Our academy expert Michael Sweeting provides his opinion on what to expect from each player:
Randall: is a converted centre-midfielder to right-back. He’s committed, full of running, a defend first full-back, strong, physical, heart on sleeve. Not very technical.
Brannagan: is an attack minded centre-midfielder or attacking-midfielder. Very clean and technical, quick but doesn’t rely on his pace, gets goals but more a support midfielder.
Teixeira: is deceptively hard working. He can play the killer ball but is more of a physical runner than a playmaker.
The common thread between Randall, Brannagan and Teixeira is their hard working, never-say-die attitude.
