PSG manager Mauricio Pochettino has come under fire in recent weeks owing to his team's poor performances. The tactician is guilty of failing to get the best out of his superstar-filled squad at the Parc Des Princes. In fact, even winning the Ligue 1 title won't be enough to cover up his failings this term.PSG's first embarrassment of the season came when they were sent crashing out of the French Cup following a defeat to Nice in January. Things got even worse after they were knocked out of the Champions League by Real Madrid in the round of 16, courtesy of a 3-2 defeat on aggregate.As it stands, things appear to be getting even worse for the French giants. The team lacked cohesion in their most recent Ligue 1 clash with Monaco last weekend and were made to pay for it with a 3-0 humiliation. According to rumors, the Parisians will likely relieve Mauricio Pochettino of his duties before the next campaign.With that in mind, we've decided to compile a list of five managers who could take over from the tactician at the Parc des Princes. They are as follows:#5 Roberto MartinezRoberto Martinez is doing quite well with the Belgian national teamThe Italian is currently working with the Belgian national team. He's been with the Reds since August 2016 and it wouldn't be far-fetched to say he's done a decent job so far. His record with the team is quite impressive, having bagged 51 victories, 10 draws and seven defeats from his 68 games in charge.Fabrizio Romano@FabrizioRomanoBelgium coach Roberto Martinez to HLN: “There is absolutely nothing - and there has been no contact with Barcelona. I want to fulfill my contract, but many things may arise along the way”. @albert_roge #FCB #Barça09:57 AM · Oct 1, 202114655686Belgium coach Roberto Martinez to HLN: “There is absolutely nothing - and there has been no contact with Barcelona. I want to fulfill my contract, but many things may arise along the way”. 🔴 @albert_roge #FCB #BarçaRoberto Martinez isn't a stranger to club football, having served as manager at West Ham, Wigan and Everton earlier in his coaching career. Should PSG end up parting ways with Mauricio Pochettino at the end of the season, the 48-year-old will definitely be among the options to replace the Argentine.#4 Joachim LowThe German is currently without a jobThe tactician made history when he led Germany to claim the FIFA World Cup in 2014, skyrocketing his reputation in the sport as a result. He ended his association with the national team last summer and hasn't taken to management ever since.Squawka News@SquawkaNewsOFFICIAL: Germany have confirmed Joachim Löw will step down as national team head coach after the Euros.11:13 AM · Mar 9, 20211464363OFFICIAL: Germany have confirmed Joachim Löw will step down as national team head coach after the Euros. https://t.co/UaJ7pS8BbIIt's still unknown what Joachim Low's next step will be. If the tactician decides to return to the dugout at the end of the season, he will surely not be short of suitors. In fact, he'll have as much probability as anyone in the race to replace Mauricio Pochettino as PSG manager.
