The winger came through the ranks at Celtic, and he has gone on to make almost 100 appearances for the Glasgow giants. However, he has failed to truly establish himself as a key player.
Therefore, a loan move was arranged in the New Year, with Johnston joining Albion for the remainder of the campaign.
And, it has turned out to be superb business for the Baggies, with Johnston scoring six goals in 10 games, as Carlos Corberan’s men take a firm grip on a play-off spot.
It’s not just an excellent goal return either, as the 24-year-old has scored some sublime individual efforts, and he is a constant threat with his pace and dribbling ability down the flank.

Naturally, that has already prompted talk about whether Albion can keep Johnston at The Hawthorns beyond the summer, as the agreement in January did not include an option to buy.
Celtic chief Brendan Rodgers has refused to give much away when quizzed on the future of his player, as he insists they will assess the situation in the summer.
Yet, speaking to FLW, Palmer explained that his former club must do all they can to sign Johnston as soon as possible, as he feels rival interest is inevitable given how the attacker is performing.
“I think this is a problem for West Brom. Johnston has had an unbelievable impact. He’s been exceptional, with six goals and one assist.
“West Brom should be looking to secure a permanent transfer, as he’s taken to the Baggies, to the supporters’ hearts and done really well. Obviously, though, there was no option to buy as part of the agreement, and that’s why Celtic have sent him out on loan.
“There’s no doubting Johnston’s ability, but he needed to get out, play regularly, and he’s done that at West Brom in the Championship. Albion are in the play-off positions but it’s going to be difficult for them to secure his services now, because he’s done so well.
