Roman Abramovich is set to give Thomas Tuchel his biggest indication that he is his main man at Chelsea. The Russian owner is preparing to finance the coach of the Blues this summer with a big kitty.

Chelsea boss Tuchel could be on the verge of landing a huge transfer budget this summer with Abramovich set to back his manager.

After January, that means the German manager has only signed one player across three transfer windows.

Romelu Lukaku was brought in from Inter Milan – for a whopping £97million – but there have been plenty of players linked.

Despite the Belgian forward’s arrival for a club record, he hasn’t had the preferred impact in the Premier League.

In 16 league appearances, the 28-year-old scored just five times as Chelsea’s title challenge all but ended in January after a string of draws.

And Abramovich wants to change that by backing his manager with a huge transfer summer, according to the Evening Standard.

The Russian owner is convinced that Tuchel is the right person to overturn Manchester City’s dominance of the Premier League.

Pep Guardiola looks set to win his fourth title in five years after many had pointed to Chelsea as title challengers this year.

He could see mega-money arrivals in the form of Declan Rice, Aurelien Tchouameni and Jules Kounde.

The latter has been heavily linked with a switch from Stamford Bridge and a move nearly went ahead last year only for Sevilla to ask for more money at the last minute.

There will also most likely be forced changes to the squad with Antonio Rudiger, Cesar Azpilicueta and Andreas Christensen out of contract at the end of the season.

That will require a few arrivals with Thiago Silva, Trevoh Chalobah and Malang Sarr the only potentially remaining centre-backs.

The latest summer craze at Stamford Bridge has seen the arrival of the likes of Kai Havertz, Ben Chilwell, Timo Werner.

Over £200million was spent but it didn’t go to plan for then-manager Frank Lampard, who was sacked in January this season.
