Robertson has struggled to nail down a regular place in the Blackpool side since arriving from Dundee United last summer.

Fenlon is confident of finalising a deal for Robertson in the next 24 hours as he looks to add to his squad before the close of the transfer window.
"We are talking to Scott and hopefully we should be able to get something done in the next 24 hours," said Fenlon.
"Until these things are over the line, you're always wary that something may pop up but we're very hopeful we can get it done.
