Arsenal are close to agreeing a fee of around £60m for Pierre-Emerick Aubameyang with Borussia Dortmund, according to Sky sources.
It is understood that talks are ongoing between the clubs, but a deal has not yet been reached for the striker.
Arsenal had a bid in excess of £50m rejected, with Dortmund’s sporting director Michael Zorc saying they would only let the 28-year-old go if their demands were met. It is understood they are holding out for £60m.
One source told Sky Sports News on Sunday night that Arsenal striker Olivier Giroud may yet be involved in a deal to bring Aubameyang to the Emirates.
Arsene Wenger said on Friday that Giroud would not leave unless another player came in.
“Arsenal have made several attempts so far [to sign Aubameyang] and they have all been rejected,” Zorc told Sky in Germany on Saturday.
“Either our demands are fulfilled, then there can be another transfer, or they will not be fulfilled and Aubameyang will play in Dortmund until the summer.”
Aubameyang was booed by a section of Dortmund fans at the Westfalenstadion during their 2-2 draw with Freiburg on Saturday and a banner in the crowd read: ‘No player is bigger than our club’.
Chelsea missed a string of chances to draw 0-0 at home with Arsenal in the first leg of their League Cup semi-final on Wednesday as the video assistant referee (VAR) stoked the tension with two important interventions.
The hosts struggled to break down Arsene Wenger’s side despite enjoying the majority of possession and will feel hard done by after crafting the best of the game’s few openings in a lively game at Stamford Bridge.
Chelsea defender Andreas Christensen wasted the best of the hosts’ opportunities, failing to find the target with two headers in the second half after Cesc Fabregas had also spurned a headed chance before the break.
Yet with limited goalmouth action, what little drama there was seemed to stem from referee Martin Atkinson referring a handful of decisions to the VAR.
The VAR system was being given its second outing in English football and was called into action in the first half to confirm Atkinson’s decision to wave away a penalty appeal after Arsenal’s Alex Iwobi went down following a challenge from Victor Moses.
It was called on again with two minutes remaining and once more confirmed the referee’s decision not to award a penalty, this time after Danny Welbeck got a faint touch on the ball when bringing down Fabregas.
With the system still in the test phase all eyes were focussed on how it would work, with Wenger voicing concerns in the aftermath about the length of time it took to confirm the referee’s decision not to award a penalty against Welbeck.
He was, however, delighted with how his side defended to leave the tie in the balance ahead of the second leg in two weeks time.
“I felt there was great togetherness, we didn’t give many chances away. I am pleased with the spirit and determination,” Wenger told sky Sports.
Arsenal came into the game without a win in their last three matches and nursing the wounds of a bruising third round FA Cup defeat to second tier Nottingham Forest, but they were resolute from the beginning in what was a relatively cagey affair.
Headed chances went begging for the hosts either side of halftime as Fabregas could only steer Cesar Azpilicueta’s diagonal ball straight at David Ospina while Christensen twice failed to find the net from close range after the break.
“We tried with all our strength to win the game,” Chelsea boss Antonio Conte said. “We created chances to score but a few times we were not so clinical.”
The winners will face either Manchester City or second tier Bristol City in the final, with the Premier League leaders taking a 2-1 lead into the second leg.
