The worst signings Chelsea have ever made including AC Milan, Leicester and Real Madrid stars

This summer transfer window will be pivotal for Chelsea as they begin a new era under Todd Boehly and his consortium.

There will be several players who will be looking over their shoulders about their long-term futures, while the whole structure of the club from a financial point is likely to change.

One of the features that made Roman Abramovich such a likeable owner to Chelsea fans was his willingness to bring in players with quality regardless of how much it cost him.

The Russian oligarch would break the bank and ensure that the best talent played at Stamford Bridge.

This summer transfer window will give us a clear picture of the ambition of the new owners.

Over the last two decades, Chelsea have easily been one of the best clubs in the world.

South-west London become home to some of the best players, who enjoyed gracing Stamford Bridge.

But in the midst of all the glory and titles, there has a lot of money that has gone to waste, with huge investment on players who ended up giving back almost nothing.

The club is currently exploring the £97.5million deal that brought Romelu Lukaku back to the Premier League, after what has been an underwhelming return for the Belgiun international.

But Lukaku does not stand alone when it comes to big money investments that have looked a pale shadow of their former selves, and in-fact there is a growing belief that several big name signings fall flat.

So with the anticipation building ahead of what will be a pivotal window for the Blues, we take you down memory lane to some of the players who came to Chelsea but were never really able to make the cut.
