Newcastle boss Eddie Howe doesn't expect a massive spending spree this summer.
The Toon are on the brink of qualifying for the Champions League next season.
"Regardless of what happens, we're not going to have a bottomless pit," he told the Daily Mail. "We will be under tight constraints. Whatever we do in the transfer market, we're going to have to be very smart. In the three transfer windows I've had, we've been excellent, and we have to continue that.
"Everyone will say, 'That's a great achievement' - but all I can think of is that next challenge coming and being prepared for it.
"You can't sit back and say, 'Right, I'm going to take a month off and go and relax on a beach'. It's the opposite - it's, 'OK, how can we best now succeed in that next phase?'. You're always on a cycle of trying to improve."
