Swansea chairman Huw Jenkins has admitted Wilfried Bony could leave the Liberty Stadium if the 'right offer' is made.
Manchester City striker Edin Dzeko has confirmed that he is in talks about signing a new deal at the Etihad.
Arsenal must decide whether to cash in on wantaway striker Robin van Persie after the captain insisted he had to leave the Emirates Stadium to win trophies.
Holland international Van Persie last night issued a carefully-worded statement on his official website revealing he would not be penning an extension to his current deal with the Gunners, which expires next summer.
The 28-year-old netted 37 goals in all competitions as Arsenal eventually secured third place, and manager Arsene Wenger recently declared the club must retain their talisman "at all costs".
However, despite meeting with Wenger and chief executive Ivan Gazidis at the end of last season and the signings of Germany striker Lukas Podolski as well as France forward Olivier Giroud, Van Persie remains unconvinced he can fulfil his ambitions with the club he joined as a raw talent from Feyenoord in May 2004.
Van Persie will turn 29 in August, and the next contract he agrees could well be his last at the highest level.
Both Serie A winners Juventus and Barclays Premier League champions Manchester City are said to be ready to test Arsenal's resolve with £20million-plus bids.
However, the Gunners - who last summer saw both Cesc Fabregas and Samir Nasri sold - could also look to hold Van Persie to the terms of his deal.
A brief statement on the club's official website read: "Robin has one year to run on his current contract and we are confident that he will fulfil his commitments to the club.
"We have to respect Robin's decision not to renew his contract.
"We are planning with ambition and confidence for next season with Arsenal's best interests in mind."
Arsenal are set to tour Asia at the end of the month, and will also play a game in Nigeria.
Whether or not their captain will now be part of the travelling squad remains to be seen.
Van Persie, though, made it perfectly clear disagreements over the direction of the club means he does not want any part of Arsenal's long-term future.
In an open letter to fans on his website he wrote: "I've thought long and hard about it, but I have decided not to extend my contract.
"As announced earlier this year I had a meeting with the boss and Mr Gazidis after the season. This was a meeting about the club's future strategy and their policy.
"Out of my huge respect for Mr Wenger, the players and the fans I don't want to go into any details, but unfortunately in this meeting it has again become clear to me that we in many aspects disagree on the way Arsenal should move forward."
The Dutchman maintained he would always "love" Arsenal, where he had "become a man", but insisted a fresh start was needed to fulfil his own ambitions.
"Financial terms or a contract have not been discussed, since that is not my priority at all," said Van Persie, who would be offered huge wages in the region of £200,000 per week at City.
"I personally have had a great season but my goal has been to win trophies with the team and to bring the club back to its glory days."
