Sunderland signed the Ukrainian centre forward in the summer to beef up their attacking options following the exit of Ross Stewart.
However, despite failing to address the Black Cats’ problems in front of opposition goal, Rusyn has earned praise for his work rate from former players.
Collins pointed out that Rusyn looks confident when he picks up the ball while running through the channels and added that the forward can be a nuisance for tall defenders as well.
However, Collins also pointed out that Rusyn needs his Sunderland team-mates to put more balls in the opposition box to attack.
