Arsenal have rejected an approach for Alexis Sanchez from Manchester City as Pep Guardiola steps up his pursuit of the Chile forward.
Press Association Sport understands that the Gunners are intent on keeping Sanchez despite strong interest from City, who are widely reported to have tabled a £50million offer.
Sanchez has entered the final year of his contract at the Emirates Stadium and Arsenal's resolve is being tested by their Premier League rivals ahead of Thursday's transfer deadline.
Meanwhile, West Brom have announced the signing of Kieran Gibbs from Arsenal for an undisclosed fee.
The 27-year-old has signed a four-year contract to become the Baggies' latest summer recruit and follow Jay Rodriguez, Ahmed Hegazi, Gareth Barry, Yuning Zhang and Oliver Burke to the club
Gibbs made over 200 appearances for Arsenal, but despite his early potential struggled to retain a regular place in Arsene Wenger's starting XI and he is expected to be the first of several departures from the Emirates before Thursday's transfer deadline.
"I watched the boys in the first few games of the season and they've got a lot of energy," Gibbs told West Brom's official website. "They've made some good signings and I feel this is a good move for me."
But it is the future of Sanchez and Alex Oxlade-Chamberlain that will really occupy the minds of Gunners fans.
City continue to appear the likely destination should Sanchez depart, while England international Oxlade-Chamberlain is a target for Chelsea.
With just two days remaining before the transfer deadline at 11pm BST on Thursday, the pair could yet complete their moves.
Both are out of contract at the end of the season, although manager Arsene Wenger has stressed on several occasions that he wishes for both to remain at Arsenal.
The Frenchman - who has spoken for weeks about the need to trim his squad - is already under pressure after Sunday's 4-0 loss at Liverpool.
Brazilian defender Gabriel was sold to Valencia last week and, as well as Oxlade-Chamberlain and Sanchez, there are several other players who may leave.
