Arsenal FC's longest-serving manager Arsene Wenger is under immense pressure to right the wrongs this summer.
Six trophy-less seasons coupled with a prospective mass exodus of star players from the Emirates makes his job even more tough this summer.
The Frenchman was successful as the manager of Arsenal until he moved from the venerable Highbury to the pristine Emirates—a move that has yet to yield a trophy for the Gunners.
For monetary reasons and the long-term future of the club, the move to the Emirates was necessary.
However, although a few regulations were inevitable in terms of transfer dealings and player wages, nobody expected Arsenal to go through a lean patch for so long with very few reasons to celebrate during the horribly disastrous period in Wenger's reign.
His reign can be classified into two epochs: pre-Emirates and post-Emirates.
On the basis of the latter part, Wenger should have got the sack by now, but he's still at the helm thanks to his early success and financial benefits to the club.
Wenger's youth policy will eventually pay rich dividends but that doesn't mean Arsenal should look into the future and discard the present.
Although Arsenal don't have the resources to conduct big-money signings, the manager can afford one or two big-money signings now and then.
That's where Wenger failed in recent years. He overlooked his wobbly defence and shaky goalkeepers for attack, and as a result paid a big price for defensive errors.
With a better goalkeeper and another established centre-back—fans have been pleading for these two signings for years—Arsenal could have mounted a sustained title challenge and in all likelihood would have won a trophy or two.
The goalkeeping situation has considerably improved this season while the defence is more or less same with an alarming rate of more than one goal conceded per game in the 2010-11 domestic season.
It's safe to say that Wenger's unwillingness to learn from his mistakes has cost the club dearly.
Although he was provided ample time to address the issues, Wenger's obstinacy dictated his sensibility playing a big part in Arsenal's barren spell.
Here are the five reasons why the Arsenal board should pull the curtains down on the waiting game and fire the reticent Frenchman.
