Chelsea have lost four of their last five league matches and are now nervously looking over their shoulder as they seek a top-four finish.

While a loss away to Manchester City at the start of that run can be excused, defeats to an out-of-form West Ham at Stamford Bridge, an out-of-form Everton at Goodison Park and an out-of-form Bournemouth again at Stamford Bridge must be seriously worrying for Frank Lampard.

Of course, Chelsea’s transfer ban has now been lifted meaning Lampard can improve the squad to ensure they qualify for next season’s Champions League.

The arrivals of Nathan Ake and Wilfried Zaha have been touted. Whether or not Bournemouth and Crystal Palace would be willing to sell next month remains to be seen, though.

But it seems Lampard is already looking ahead to the summer transfer window.

And the Chelsea boss has identified a shock position that he’s keen to strengthen.

Sources close to the club have told Bleacher Report that Lampard wants recruitment staff to start looking for a new goalkeeper for next season.

The report states that Lampard won’t have much say in the search as it’s not an area of expertise. However, he wants an option to replace the world’s most expensive goalkeeper, Kepa Arrizabalaga, due to his recent poor performances.

The Spaniard has looked unconvincing at times this season, especially during last weekend’s 3-1 defeat to Everton, and has saved just 56% of the shots he's faced.

He was also blamed for Valencia’s second goal during their 2-2 Champions League draw earlier this month.

GIVEMESPORT’s Rob Hoskin says: There’s no doubt Chelsea will be expecting better performances for the costliest goalkeeper in world football. When you look at the performances Alisson is producing for Liverpool - who cost a few million less than Kepa - you have to agree that the Chelsea ‘keeper needs to be doing more.

But will the Blues realistically replace him?

Firstly, they would need a club willing to bid around the £71.6 million that Chelsea paid for him in the summer of 2018. With him in this kind of form, that isn’t going to happen and the club are set to take a big financial loss on him.

That’s something they will be reluctant to accept.

At 25, Kepa is still relatively young for a goalkeeper and the west London club must stick with him for now.
