Martin Keown says Arsenal will be unable to retain Pierre-Emerick Aubameyang and Alexandre Lacazette - if Unai Emery remains at the club.
The star striking duo will reportedly look to leave the Emirates in the summer if the Gunners fail to qualify for the Champions League.
"If they decide to stick with Emery then the manager has big decisions to make himself," he said.
"I warned against Arsenal signing David Luiz in August and I wonder if he should be taken out of the team now.
"Certainly star players like Pierre-Emerick Aubameyang and Lacazette will not be signing extensions unless things change."
