In Chelsea’s attacking line-up, the right-winger spot has been a problem.

While Eden Hazard and Alvaro Morata occupy the other two spots in the front-three, the right side remains undecided.

Willian and Pedro have rotated starts in that spot, but neither have staked a serious claim to start regularly.

But when Chelsea face Crystal Palace on Sunday, they’ll be facing the perfect player to fill that role when they come up against Wilfried Zaha.

Despite a failed move to Manchester United in 2013, Zaha has easily become Crystal Palace’s best player.

The split between their record when he plays and when he doesn’t is astounding, highlighting their dependance on him.

Although a winger, Zaha is their attacking focal point, and suffers from heavy challenges from defenders as a result.

But, Maurizio Sarri should seriously consider making Zaha his third signing at Chelsea as he could really add something to his team.

In a team with Hazard, the focus wouldn’t solely be on the Ivorian, which could see him flourish.

A problem that Sarri’s team have encountered – although unbeaten – is their inability to break down stout defences.

And Zaha’s tight control and ability to dribble in cramped conditions could help Sarri’s team succeed.

He has previously been connected to a move to Stamford Bridge, but nothing came of it.

But if Palace continue to falter, Sarri should look to add him to Chelsea’s squad in January to maintain their title push.
