Right-back Darnell Furlong was an early arrival at Albion in the summer of 2019, after spending more than a decade coming through the ranks at QPR.
The defender signed his first professional contract with the Loftus Road side in March 2014, making his Premier League debut just under 12 months later aged 19.
A first loan spell came with Northampton Town during the early part of the 2015/16 season as Furlong contributed 10 appearances to the eventual League Two winners.
He then spent the second half of that campaign with another fourth-tier side, Cambridge United, playing every minute of every league game following the temporary switch in January and helping them claim a ninth-placed finish.
After returning to QPR that summer, Darnell was sent out to gain further first-team football at Swindon Town in League One for the 2016/17 challenge.
The Luton-born full-back, who is the son of former QPR, Birmingham and Chelsea striker Paul Furlong, made 28 outings for the Robins in all competitions before Ian Holloway recalled him to London.
He featured in 14 matches for the Hoops during the back end of that season and then went on to play a total of 24 times for Rangers the following year.
The 2018/19 campaign was his most successful in terms of game-time to date, with manager Steve McClaren and caretaker John Eustace employing him in 29 fixtures across all competitions.
But Furlong's career took a turn for the better when Albion secured his services during the summer of 2019. The full-back was regularly involved under Slaven Bilić, making 33 appearances and netting two headed goals as the Baggies returned to England's top flight in July 2020.
Darnell's first full campaign of Premier League football saw him make 36 appearances and score his first top-flight goal - a memorable volley against Newcastle United in December 2020.
Furlong's aerial prowess was further emphasised during his first term of regular Premier League football, as he ended the 2020/21 campaign as one of the division's best players for aerial duels won.
