Arsene Wenger has been at the helm of English Premier League club Arsenal's affairs for 15 years now and is one of the longest serving managers in the league. Now, however, although he has led the club to three Premier League titles and four FA Cups (in addition to being the first non-British manager to win the domestic double (the league and the cup in the same season), twice, in 1998 and 2002, Wenger has recently hinted that he may leave the Gunners at the end of the current season.

Even if he chooses to stay, Wenger may be asked to leave by the board, given that the club has been on a title drought for several seasons now.

The question then is - who will replace the Frenchman?

Here are the five best choices.

The 44-year-old Mainz 05 player and the current Borussia Dortmund boss could be a great choice for the Gunners, should Wenger decide to depart. The German, Klopp, is a manager with a growing reputation and Dortmund, under his management, clinched the Bundesliga title last season.

Remi Garde, 45, is currently the manger of Ligue 1 club, Olympique Lyonnais, having only joined them last season. A former Gunner himself (he joined the club in 1996 and was part of the 1997-98 double-winning squad), he was previously linked with the post of Director of Football at the Emirates.

The current head coach of the French national team, Laurent Blanc, 46, replaced Raymond Domenech in the wake of a disastrous 2010 FIFA World Cup for the French. During his playing days for the national team, he scored the first golden goal in World Cup history, against Paraguay. Blanc won the 2008-09 Ligue 1 championship title and the Coupe de la Ligue with Girondins Bordeaux in only his second season as the club's manager. That year, under Blanc, Bordeaux won the final 11 games of the season, setting a French league record for the most consecutive wins.

Carlo Ancelotti, 52, is one of six men on the planet to have won the European Cup (now the Champions League) as both player and manager. The Italian tactician was appointed manager of AC Milan in 2001 and won the Scudetto (the Italian league title) in 2004, the Champions League in 2003 and 2007 and the Coppa Italia in 2003. In 2009, in his first term as manager of English club Chelsea, Ancelotti became the second non-British manager to win the domestic double. He is currently not employed by any club and could be a good option for the Gunners.
