Steven Naismith insists Kris Boyd can transfer the goal-scoring prowess he displayed at Rangers to new club Middlesbrough.
The duo were team-mates at Kilmarnock before heading to Ibrox, and fellow forward Naismith is fully aware of what his former colleague has to offer.
Naismith has witnessed Boyd finish top goalscorer every season for the Scottish champions, and he is backing the 26-year-old to carry that ability to Boro after joining the Riverside club on a two-year deal.
"I think he will score goals wherever he plays and he has shown that throughout his career so far - starting off at Kilmarnock, coming to Rangers and then on the international scene," said Naismith.
"It's another challenge for him and I'm sure he will score many goals for Middlesbrough.
"He has been in Scotland a long time, with Kilmarnock and Rangers, and it's probably just a different challenge for him."
Boyd's decision to depart Rangers for npower Championship club Boro might seem surprising given the forward previously attracted interested from Birmingham and was linked with Wigan and Newcastle.
But Naismith believes Boyd joining a second tier club does not mean a Premier League move was not an option.
"I think Boydy had a lot of offers so it would be wrong of me to sit here and say he didn't get a move there because he wasn't good enough," he said.
"He might have got a few offers from the Premiership. But I think he has looked at the full picture and decided the best move for him and his family was Middlesbrough.
"I don't know if it's a step up, a step down or whatever. It's more a different challenge, it's another league for him to play in.
"I'm sure if he does well at Middlesbrough, there is a chance he could be playing in one of the best leagues in the world. And that will be his motivation for people who are saying it's not a step up for him."
Naismith is hoping to help fill Boyd's prolific boots at Rangers now that the forward's departure has been confirmed.
"It's a big opportunity for everybody who plays up front at the club, definitely," he added.
"Boydy is a hard guy to follow, with his scoring record.
"But we've got guys here who can score goals and they have proved that so I'm sure we will do all right."
