Blackpool challenge Middlesbrough for Liverpool's Shelvey
Middlesbrough are also keen on the England U21 international.
Ollie said: "We have already had him and I know what the lad is capable of. I really like him.
"He made a big impression when he was here and he wouldn't have gone back had there not been an injury at Liverpool.
"We'll keep monitoring it and hope that we might be able to get something done."
