The former forward believes the Gunners still need a world class striker.
The Gunners were widely expected to be title contenders this season after finishing the last campaign as one of the in form sides in Europe.
Things were going well for them until the turn of the year too, as they topped the Premier League and looked to be contenders for the title.
Instead they have fallen away in 2016 and now face a fight to ensure they finish in the top four and continue in the Champions League next season.
And as far as Shearer is concerned, they will never win the title until they sign a world class striker.
“Arsenal are consistent, they finish third or fourth every season,” he told Match of the Day 2.
“They won’t win the league this season, and they won’t win the league until they sign a world class striker who can get 25 goals a season.”
“I’ve been saying all season they’re two players short and my view hasn’t changed on that.”
The striker position has long been one that Arsenal fans have called for the Gunners to improve, alongside the defensive midfield role.
Olivier Giroud has shown he can score goals this season, but his tailing off in the second half of the campaign shows he may not be the world class forward they need.
Similarly, Theo Walcott has failed to impress in a central role, further highlighting how the position should be the club’s main focus this summer.
