Chelsea owner Roman Abramovich is prepared to hark back to his early days in west London and get behind manager Antonio Conte to the tune of a £200m transfer budget this summer as the Blues gear up for Champions League football, according to The Observer.

What's the word?

As part of a new deal for Chelsea's title winning manager, owner Roman Abramovich is prepared to go big in the transfer market in the pursuit of four marquee signings this summer.

Antonio Conte has continually made it clear this season that he plans to have a similar impact in the Champions League next season to that on a domestic level in his maiden Premier League campaign, but to do that he'll have to spend money.

One factor in Chelsea's success this season has been their ability to play a settled starting XI with no European football to speak of, however, with the Champions League returning to Stamford Bridge next season a swelling of the ranks is needed.

Who are they after?

Whilst more depth is needed, Conte won't just buy for the sake of bolstering his squad, the Italian needs, and will demand, quality.

The Observer claim that the club are looking into deals for each of Everton striker Romelu Lukaku, Arsenal star Alexis Sanchez, Monaco man Tiemoué Bakayoko and sought-after Southampton defender Virgil van Dijk.

It is fairly clear that it would be almost impossible to bring in all four this summer. Arsenal are unwilling to sell Sanchez this summer with Arsene Wenger persisting with the line that so long as he is under contract he'll be an Arsenal player. Furthermore, should they cave it is far more likely they'll opt for a bidder outside of the Premier League.

Even if a deal for Sanchez cannot be reached, deals for three or even two of their main targets would represent a strong summer of business for the Blues as they ready to do it all again next year.
