Chelsea's Premier League campaign has taken a turn for the worse in the past three match days. Their defence struggled in the clash with Swansea but they managed to fight back for a point.

However, it got worse for the Blues as they were well beaten by Liverpool in the Friday Night football clash last weekend before being demolished by Arsenal in Saturday's evening kick off.

Whilst it is Chelsea's defence that seems to require the most improvements considering the mass leakage of goals, Alvaro Morata could have been the signing to help Chelsea wrestle back the Premier League.

Their main reasons are threefold...

He would complement Costa perfectly

Like the majority of Premier League sides nowadays, Chelsea play a one lone striker. However, that's not to say that having more in the locker isn't worthwhile and Morata is one of the best strikers in the world.

Instead, Chelsea signed Michy Batshuayi and whilst the Belgian striker has impressed during his appearances from the bench, there's no denying the quality of Morata in comparison.

Additionally, whilst Morata is not seen as one of the fastest players, he has a clinical edge to him which we we're unconvinced the Belgian star possesses.

Another Spaniard to improve the camaraderie

Like Manchester United, Chelsea have quite a collection of Spaniards and they are known for gelling quite well together. The trio at Manchester United (Ander Herrera, De Gea and Juan Mata) are known to be great friends off the pitch too which considerably improves their connections on it.

If Chelsea had signed the Spaniard he would've been their sixth Spanish player, which would have undoubtedly improved squad morale.

They already have Cesar Azpilicueta, Cesc Fabregas, Pedro, Diego Costa and Marcos Alonso who are all in and around the Chelsea starting XI and adding another Spaniard could have made it even better for the Blues.

Furthermore, there are many Spanish speaking players such as those from Brazil like David Luiz, Oscar and Willian.

He would've been the marquee signing

Nowadays, there is always talk of clubs making 'marquee' signings. It is big names that fans are able to get excited about and impress pundits and colleagues alike.

Chelsea's marquee signing this summer was probably David Luiz which was more controversial than it was impressive. It certainly felt like a panic buy and was not the sort of player that Antonio Conte would've picked.

The Blues also signed N'golo Kante who has impressed, but David Luiz was the biggest name the Blues signed.

If they are going for the title, you'd imagine that they have to do a bit better than that. Chelsea's defending has been shaky at best and Luiz is not a defender you bring in to shore it up. He takes risks and is a bit erratic.

Obviously, Chelsea still have a lot of work to do to return to the form that brought them the Premier League in 14/15.

Signing Morata would have been the starting point for an improved and successful campaign.

Maybe next summer..
