Luton have signed former Peterborough and Brighton striker Craig Mackail-Smith on a two-year deal.
Norwich City have completed the signing of goalkeeper Jake Kean following his release from Blackburn Rovers.
The England defender is close to entering the last year of his contract with the FA Cup finalists and has yet to fix up a new deal.
He has told the Daily Telegraph that he wants to stay, but claims he is not naive enough to think that is assured.
And, with the World Cup on the horizon, the former Everton man wants a first-team place to show national boss Roy Hodgson that he is up to the job.
He said: "If someone said when I signed here 'you're going to win the Premier League, get to two FA Cup finals and represent your country in the Euros' I'd have snapped their hand off.
"So now to go into the final year of my contract uncertain about my future is quite strange. I'd love to stay. My wife's pregnant, we've just moved house, the kids are happy at school. But I'm not naive. When you've achieved all that and you're going into the last year of your contract your future might be elsewhere.
"I can't afford to go into a World Cup year being uncertain of whether I'm going to play [regularly] here.
"I feel I've done enough for the club to demand a bit of respect in terms of they come and tell me what they want, whether it's a new deal, which I would be delighted to sign, or [to go] elsewhere.
"I'm very respectful of the club with what they've done for me, how they were persistent when Everton were digging their heels in to keep me. I owe a lot to the club. I also feel I've done enough to demand a bit of respect to not see speculation about my future."
