Why Chelsea's defensive issues are here to stay

Maurizio Sarri has got off to a dream start in England with two wins in his first two games as Chelsea manager. While the 3-0 victory against Huddersfield was relatively comfortable, the win over Arsenal threw a massive scare.

Against the Gunners at Stamford Bridge, Sarri's men flew off the blocks and took a quickfire 2-0 lead. However, in the last quarter of the first, Arsenal managed to equalize. In those 15 odd minutes, the North Londoner's missed a series of sitters or else they could have easily scored five goals.

While Chelsea's attacking play has looked fluid and already started to reminisce about the Italian's famous Napoli team. However, defensive issues are visible to one and all. Chelsea's problems at the back might not have an overnight solution, here is why:

#4 Change in formation

From Antonio Conte to Maurizio Sarri, Chelsea have overseen a massive tactical change. While both the coaches are from the same country, their style of football is on extreme ends of each other. While the new boss favors a traditional four at the back system, this Chelsea side is used to playing with three central defenders for the past two years. For defenders more than anyone, this change is the biggest one. For obvious reasons, the art of defending in both systems is completely different and it will only be natural for the backline to take time getting used to it.

The defenders have just not seen a change information but also in the roles, they have in the squad. On the right-hand side, after playing at left back for three years and center back for two years, Cesar Azpilicueta has gone back to playing as a right fullback. While this is his natural position, the fact that the Spaniard has not played there for five years cannot be ignored. Getting used to the needs and demands of playing at yet another new position is certainly not going to be easy for one of Chelsea's most consistent performers from the past few years.

On the left flank, the story with Marcus Alonso is not too dissimilar. The 27-year-old is barely used to playing in a back four. Ever since his arrival in West London, Chelsea has used him as a 'wingback'. Prior to his move, Alonso played in the same position at Fiorentina. The former Bolton defender is almost an alien to the 'fullback role'. His defending was a cause for concern even with the protection of an extra centre back. In his new role, Alonso will have to defend a lot more, something that is bound to cause trouble. How much longer can his goals make up for it remains to be seen.

For Central defender's, more times than not the partnership is more than individual abilities. So far, Sarri has opted for a defensive pairing for David Luiz and Antonio Rudiger. Due to Luiz's exile from the side last season, both have barely played with each other. The academy's golden boy Andrea Christensen is the one waiting in the wings and even he has barely played together with either of Luiz or Rudiger. In any case, the centre back pairing needs to get used to playing with each other and form a chemistry.

#2 Tactical Change

As Maurizio Sarri has been quick to an emphasis on, it's not just the defender's who are faulting but the entire team in the defensive process. The change from Antonio Conte to Maurizio Sarri has just not been in formation but also in approach.

The Blues have transformed from a low block side to a high pressing team. In this system, the whole team needs to work in cohesion to press high up the pitch and a lack of coordination can cause the whole defensive system collapses like at Stamford Bridge last week. These are early days and with Chelsea players still learning the system, these things are bound to happen

For Defender's, a high pressing style is completely different to what they were used to previously. Under Antonio Conte and Jose Mourinho, Chelsea usually used to drop deep and defend in numbers. However, now playing a high line under Maurizio Sarri, the back four will not have the same protection and face a completely different challenge. Only time will tell whether they can cope with or whether Chelsea needs reinforcements in the backline.

The footballing philosophies of both Jurgen Klopp and Pep Guardiola are quite similar to Maurizio Sarri. From experience in the country, it's clear that the adaption of a high press and expansive style of football in England takes its time. For Jurgen Klopp, it took more than two years to have a backline that could be trusted.

While Manchester City's record-breaking season is fresh in everyone's mind, the struggles Pep Guardiola had in his first year must not be forgotten. The Citizens conceded four goals to both Leicester and Everton away from home. Do not be surprised if Chelsea face a few similar results in Sarri's early days.

However, the key for Chelsea fans and owner is patience. In the cruelest way possible, the Stamford Bride faithful have learned how unsustainable success built on defensive football is. The need for a cultural revolution at the club is apparent to one and all. Everyone around Chelsea must be ready to go through the hard part of the process.

If given time and patience, Chelsea could reap rewards from Sarri's work for a long period of time. Ultimately, the Blue's fan must remember, he did get it right at Napoli. So far positives have been a lot more than the negatives and the minor scare against Arsenal must not take the focus away from that.
