Sunderland manager Steve Bruce has admitted that his club's bid to sign Tottenham Hotspur striker Darren Bent has become complicated by interest from other clubs.
The 25-year-old England international voiced his own frustration with delays in the deal on Friday, with Bruce also concerned that an agreement has still not been reached.
He told the Sunderland Echo: "It's a bit frustrating because we thought we had a deal done and we were close to getting a deal done. But it just hasn't happened yet.
"That's frustrating, but we'll keep trying. There's obviously got to be a time when there's a cut-off, that's for sure, but we'll see what develops over the next two or three days.
"We do have other targets - I wouldn't be doing my job if I wasn't looking at other players. If it comes unstuck, we'll go on to the next one.
"Are Spurs playing hard ball? Yes - you can put that on the record. You wouldn't expect them to do anything else.
"There comes a time and place to call it a day if we're miles apart on a valuation.
"I don't think we are so we'll see what develops, but it has been hard going and it has been tough."
