No Chelsea fan needs reminding of last year’s extraordinarily disappointing season, nor will they be likely to forget it in a hurry.

While many are still at a loss as to how the runaway champions of 2015 were sitting just above the relegation zone midway through the 15/16 campaign, others will simply want to look forward to a new era under yet another new, untested foreign manager.

Antonio Conte has a difficult job on his hands to try and reinvigorate a club that was on its knees for large parts of last season. And one of the best ways of making yourself an instant hero is to bring in a big name, budget busting signing.

We list five reasons why Chelsea need to make a marquee signing this summer...

Energise the fans

Chelsea fans

It has been a trying 12 months for Chelsea fans.

Having to watch the former Champions plummet into mediocrity, losing a dozen league games along the way. It was not a pretty picture at Stamford Bridge.

Now may be the time for Conte to re-ignite the passion in the fans by bringing in a big name to provide a major boost ahead of what could be the most competitive Premier League season for sometime.

Continue the revolution

John Terry

Since Petr Cech, Frank Lampard, Didier Drogba and Ashley Cole left the club, John Terry has cut a lonely figure in flying the flag for the old guard who achieved so much at Chelsea.

While the new generation at Stamford Bridge began with success, it has since spiralled into disarray.

Antonio Conte will want to continue the overhaul at the club and bringing in new, exciting marquee signings would be the perfect start.

Prove they are a danger again

What Chelsea so clearly lacked last season was a fear factor that they had so often in years’ past.

Any team in the Premier League believed they could get points at Stamford Bridge last campaign and many of them duly did.

A marquee signing could bring that fear factor back to their West London home, especially if that marquee signing performs to his best.

Keeping the better players happy

Diego Costa

Diego Costa, Thibaut Courtois, Eden Hazard; just some of the star names rumoured to be leaving Stamford Bridge this summer, with no Champions League on the horizon to bleak a prospect.

A marquee signing would not only demonstrate a real show of intent from Conte and Chelsea, despite missing out on the most prestigious competition in European football, it may also convince the other big name stars that they should stay in West London for now.

Spend. Win. Repeat

Roman Abramovich

Perhaps the most obvious reason as to why Chelsea should make a marquee signing this summer is the fact that it has worked so well for them in the past.

Granted, last season was a bizarre anomaly, but the merry-go-round of superstar players that Chelsea have recruited for big money, has won them four Premier League titles and a Champions League trophy; it should be no different this summer.
