Arsenal need to sign a killer striker like Luis Suarez or Robert Lewandowski in the summer, according to Thierry Henry.

The Gunners legend named the prolific pair as the type of players who would elevate his former team to title winners although he admitted it is difficult to sign such elite forwards.

Arsenal have once again fallen short in their bid to challenge for the Premier League this season to extend their spell without the title to 12 years.

They failed to score against Sunderland on Sunday in a goal-less draw at the Stadium of Light, which leaves Arsene Wenger’s team fourth in the league.

Olivier Giroud is Arsenal’s leading scorer with 20 goals in all competitions, but he has scored only twice since January and both of those goals came against Championship side Hull in the FA Cup.

Behind the Frenchman, Alexis Sanchez has scored 16 goals, while Theo Walcott is third top scorer with nine strikes.

These numbers pale into comparison with the likes of Suarez and Lewandowski, although Henry explained clinical front men offer more than just goals.

“It’s not always about the number of goals you score,” Henry told Sky Sports 1 during coverage of Arsenal’s clash against Sunderland on Sunday.  “When you know you have a striker that can win you the game, you defend better, away from home in Europe, away from home in the Premier League. You think, ‘let’s keep it tight, that guy can win it for us’.

“That’s the type of striker they need. Is Welbeck a great goalscorer? We still don’t know as he hasn’t had a full season at Arsenal. Can Sanchez be that guy? We know what he did a year ago. Did he perform this year? No, for injuries or whatever.

“They need to find that striker, but where do they find him? Where do you get Suarez or Lewandowski? Where do you get that guy who’s going to score the goals when it matters? They’re already playing for the best teams in the world.”

Suarez, who came so close to joining Arsenal in the summer of 2103, has scored an astonishing 53 goals in 49 games in all competitions for Barcelona this summer, including 34 in the league to top the La Liga charts.

Lewandowski has also had a prolific season for Bayern Munich, accumulating 38 goals in 45 matches in all competitions, including 27 in the Bundesliga.

In other Arsenal news, the Gunners have reportedly offered a 24-capped international midfielder to West Ham ahead of the summer window.
