Pompey were among those adding to their ranks, with head coach Danny Cowley bringing in young Manchester City keeper Gavin Bazunu on a season-long loan on Thursday.
That’s after he landed former Luton and Millwall midfielder Ryan Tunnicliffe on a free transfer last weekend.
Both deals take the Blues up to five new arrivals so far this summer.
More are expected to follow suit.
But until then, here’s a round-up of the business concluded over the past week in the third tier – including Craig MacGillivray’s move to Charlton on a free transfer.
