Brentford boss Mark Warburton beleives new boys Andrew Gray and Moses Odubajo can only get better with the Bees.
The pair, thought to have cost the club in excess of £1million, signed deals at Griffin Park on Friday to add to the arrival of Spanish midfielder Marcos Tebar Ramiro in a week that saw striker Clayton Donaldson confirm a move to Birmingham City.
Striker Gray, 23, put pen to paper on a three-year contract having scored an impressive 30 goals in the Skrill Premier for Luton Town last term, while 20-year-old right winger Odubajo arrives - also on a three-year deal - after netting 16 times in 116 appearances for Leyton Orient.
Warburton, who takes his side on a pre-season training camp to the USA this week, said: “We are always looking to add value to the playing squad with individuals who can make significant contributions both on and off the pitch and who have excellent development potential.
"Andre has just completed an outstanding season in helping Luton achieve promotion and a return to the Football League. He has tremendous pace, good movement and a clear eye for goal.
"Moses is a player we have been looking at for the past few months and is a young player with a lot of development potential."
