Sunderland have completed the signing of Celtic right-back Adam Matthews for a fee of £2million.
Diego Poyet is determined to establish himself in Slaven Bilic's West Ham side this season and avoid another loan spell.
Paul Lambert insists in-form Aston Villa strike duo Christian Benteke and Andreas Weimann will remain with the club next season.
Lambert knows keeping hold of the pair and other key players is vital as part of his long-term project to rebuild Villa - and he has the backing of club owner Randy Lerner.
It will be a reversal of Villa's trend in recent seasons of selling leading performers such as Gareth Barry, James Milner, Stewart Downing and Ashley Young.
Benteke has scored 17 goals since his £8million move last summer from Genk and the Belgium international has been linked with a host of clubs.
Weimann has netted 11 goals in his first full campaign of top-flight football and has been offered a new deal by Villa.
Lambert said: "Do I think Weimann and Benteke will be at Villa next season? Yes, yes. I think they want to be here. I've spoken to the lads as well and they've been great with it.
"There is no point in trying to build something if it (players) keep on going away.
"There is no point in coming in for one year and, after that, the lads go away again. I don't think that is building for any sort of future.
"Do I have the final say on it? Oh yes. I've got to - but Randy (Lerner) has been great with me.
"Everyone knows the situation. If players do well, then teams speak about them. Everyone knows the situation. Whether it is true or not or agents fabricate things remains to be seen.
"When I first came in here, we sat down and explained what I thought. Randy was right behind it, no problem at all.
"He has been excellent with us. There is no point in building something, if a year later it (a player) goes. I don't want to go back to square one."
Weimann has only 15 months remaining of his current contract.
Lambert said: "I spoke to Andy's agent a couple of months back.
"I know what is happening and Andy knows what is happening.
"His agent knows what is going on. There is no problem at the minute. Am I confident Andy will sign? Yes."
Lambert hinted Benteke may also be offered a new deal this summer after his successful debut season.
He said: "I might give him a fiver more. Being Scottish, that is generous!
"I think you do that (reward players) with most lads who are performing well for you.
"You just don't want people to become comfortable or lose that hunger. I don't want a monetary thing to over-rule success."
