Arsenal would simply sign a better player if Pierre-Emerick Aubameyang completes a transfer to Manchester United this month.
That's the opinion of Jens Lehmann, who doesn't believe the Gunners should fear losing the Golden Boot winner in this summer's transfer window.
Aubameyang was linked with a shock move to Old Trafford earlier in the window, but speculation has since cooled.
Lehmann told DAZN: "If you finish fifth [in the league] you can sell players.
"If he [Aubameyang] was to go to United, a new player would come in who could do better. Arsenal's goal shouldn't be to finish fifth or sixth."
Lehmann won the Premier League and FA Cup during his time at Arsenal, but the club has since fallen out of the Champions League places.
On the club itself, the German added: "All of the guys playing for Arsenal are good but they need to win something.
"They were in the Europa League final last season and lost. Obviously it would have been good if they had won it.
"Their finish in the league season was disappointing as well. Even though they had the chance to secure fourth place, or even third place, they didn't.
