Squad shaping to hot up later in June.
Conversations are ongoing with transfer targets, while offers are still being considered by a couple of current U's players.
He told U's Player: "We had talks with them right up until the offers went to them and that is where we have left it.
"I'm pretty sure that they're still away with their families at the moment and things don't start to hot up until players come back.
"We're into June now and things start to move a little bit quicker in the second half of June.
"Players want to be at clubs for the beginning of pre-season so in that period of a couple of weeks, things will progress quickly."
