The Glasgow Rangers forward was a key part of Mark Warburton's squad at Ibrox this past season.
The 26-year-old's stunning first year at Ibrox saw him score 20 goals in just 25 league games to help the Light Blues bag the Scottish Championship title.
And Johansson explained that the forward's ability to take his chances should enable him to prove just as effective at the highest level, even if they are coming up against better teams.
"I watched Martyn play a lot of times this season and he is a great finisher," he told the Evening Times.
"Rangers will create chances in the Premiership, there is no doubt about it, because they are fantastic going forward. They have shown that in the league and the cups.
"They will create chances and I have no doubt that Martyn will get goals again.
"He is difficult to mark when he comes in off the wing and he is capable of playing in several positions. He will score goals again for Rangers next season."
With the business that Mark Warburton has done so far in the transfer window seeing the Gers' midfield significantly bolstered, it seems likely that the former Sunderland man will have the number of opportunities that will allow him to repeat this past season's tally.
Joey Barton's work-rate should enable the full-backs to be as dangerous going forward as they were this past campaign, while the likes of Josh Windass and Jordan Rossiter should bring a creativity that sees defences unlocked regularly.
And if Waghorn is capable of matching last season's tally - which is all the more impressive given that he spent a significant part of the campaign out injured - then Rangers will surely need little time to re-establish themselves as a team capable of challenging for the title.
