Arsene Wenger has revealed a few secrets about Arsenal's transfer plans.

After watching his side lose to bottom-placed Swansea City 3-1 on Tuesday night, the Frenchman was quizzed on the deal for Borussia Dortmund striker Pierre-Emerick Aubameyang.

"We will know more about that tomorrow morning," said Wenger.

Aubameyang was pictured at Dortmund airport on Tuesday heading for London. The 28-year-old will wait at Arsenal's London Colney training facility while Dortmund work on finding a replacement for him.

His move could hinge on Olivier Giroud's departure. The 31-year-old was on the bench for the Swansea defeat.

When asked if it was a possibility Giroud had played his last game for Arsenal, Wenger replied: "It's a possibility."

A deal with Chelsea for Giroud is being negotiated, and if completed, Dortmund could have their Aubameyang replacement as Blues striker Michy Batshuayi would be free to join them.
