The Seasiders have had a summer overhaul under Neil Critchley, with 15 players arriving so far. It’d be no surprise if there’s more activity at Bloomfield Road. However, Critchley has ruled out any further new faces or outgoings. Fringe midfielder Jamie Devitt is one that could depart, with League Two Barrow interested.
