The striker has been linked with a host of top European clubs after apparently growing unhappy with a lack of Champions League football.
Aubameyang has just over 12 months remaining on his deal at the Emirates and could force the club to cash in if he doesn’t commit to a new contract.
Bacary Sagna has urged Arsenal not to sell star man Pierre-Emerick Aubameyang this summer
Sagna believes it would cost Arsenal £150 million to replace the striker if he departed
Sagna says Gunners mustn’t repeat the mistake they made when they sold Robin van Persie
Sagna says Arsenal can’t afford to lose the striker and must avoid selling yet another star player as they did during his time at the club.
‘He can’t go now because are on the way to building something strong,’ he told Goal.
‘So don’t spend this £150m, just spend £50m and give it to him. It’s the same as van Persie and I think you have to learn from that situation.
Sagna has hailed Aubameyang’s improvement and says he’s now the best striker in England
‘Auba deserves it. I’m not saying that because of his name or because he has scored a few goals. He’s the best striker in the league.’
Sagna has also admitted he was previously reluctant to praise Aubameyang but says he has been impressed with his improvement at Arsenal.
‘One year ago someone asked me if he was world class and I replied no,’ he added.
‘Some people were not happy about my answer, but to me he had the potential to be better and to be more clinical.
‘One year later, yes he is world class because every time he is in front of goal he scores.’
