Arsenal legend Sol Campbell says Pierre-Emerick Aubameyang should seek assurances over the club's future plans before signing a new contract.

The 31-year-old star forward will be a free agent next summer, and Campbell thinks he needs to be assured of the club's desire to win trophies.

Campbell told Stadium Astro: "He's got to settle down and have a conversation with the manager and he needs to have a clear understanding of what they're looking to spend, who they're trying to get in.

"It's going to come down to trust, can he trust the club to say, 'right we are looking for x, y and z, we're going to bring two or three players in' and I think they'll push us on to really challenge for the top four, or really you never know [with] the Premiership.

"He needs to sit down with his people and have a serious conversation about where the club is going in the next two or three years, because he hasn't got five years, six years to say let's see how it goes, he needs almost instant success now."
