Rumours have been rife on Tyneside that Geordie Carroll, 23, hankers for a move back home.
Perch said: “I can see a time when Andy may want to come back to Newcastle. He’s only young and has a lot of playing years in front of him.
“He’s a Geordie lad and had a good rapport with everyone at the club. The fans would welcome him back but it is up to him.”
