The managers with the most to prove this season

For Mourinho and Klopp this season is the time for them to prove their worth

Managing two of the biggest teams in the world can't be easy as Manchester United's Jose Mourinho and Liverpool's Jurgen Klopp would attest to. As different as the two managers are in their footballing philosophies Mourinho and Klopp find themselves in somewhat of the same situation for the upcoming season.

Both managers will be entering a critical juncture in their respective managerial careers having some expectations to fulfill.

For Mourinho things haven't been looking up at Manchester United where despite winning two trophies in his first season and finishing behind Manchester City last season the Portuguese manager hasn't won over many fans with the way United have gone about their business.

The Red Devils started the 2017/18 season looking like they would be genuine title contenders, but as the season progressed United's inconsistencies and overly defensive nature held them back from succeeding.

Further still how Mourinho has gone about utilizing his team has been a point of frustration for many fans.

With Juan Mata, Anthony Martial, Alexis Sanchez, Romelu Lukaku and Paul Pogba United should have a fairly potent attacking force, however, Mourinho's preference to defend at all cost takes away from these players' strengths especially Paul Pogba.

Leading into his third season at the helm of the Red Devils there have already been signs of a repeat performance of the acts that lead to him exiting Chelsea and Real Madrid in not so pleasant terms.

Mourinho has cut quite the frustrated figure during preseason bemoaning United that the club haven't loosened the purse strings for him to procure more players to United's cause.

This is despite having already spent over € 400 million so far in his tenure as United manager and there are now questions about whether Mourinho is the right man to restore United to their past glory.

For the upcoming season Mourinho faces mounting pressure to succeed and goes into this season knowing that he will not only be fighting for his job, but also his reputation as a winner.

Despite having won numerous trophies wherever he has gone, it isn't too much of a stretch to see that if things don't work out at Old Trafford for him he might very well be looking at his last job managing a club of United's calibre considering his tendency to implode when things don't go his way.

Just like Manchester United Mourinho has to earn his way back to the top but it seems he's still living in the past and very soon could find out he's not that special anymore.

Juregn Klopp will also face scrutiny depending how the season goes and expectations are high although he may not be under the same pressure as Mourinho.

Klopp's Liverpool have been a work in progress with the German taking the Reds from Thursday night Europa League football to the Champions League final in just two seasons.

Last season the Reds secured successive campaigns in the Champions League for the first time since 2009 and while it represents progress things could have been much better.

Liverpool haven't won a trophy since 2012 and have played in three finals under Klopp losing them all with the most recent being their Champions League final defeat to Real Madrid in May.

As improved as Liverpool have been under Klopp their inability to win trophies counts against the German which has led some to question if in fact he is the real deal.

Some of the results have come down to Liverpool not having the right players in place to challenge the very best as evidenced from last season where they fell away towards the end of the league campaign despite at one point being only a few points off second place Manchester United to only finish in fourth.

This season Klopp won't be able to use that as an excuse as the club have been at the forefront of transfers in the summer window. Liverpool have spent £ 176 million this term in bringing Xherdran Shakiri, Naby Keita, Fabinho and Allisson over to Anfield and nothing less than the Premier League title or Champions League will be enough for supporters this time around.
