Michael Ballack has insisted that Timo Werner will fit nicely into Chelsea's starting lineup and has tipped his former club to continue spending money.
The Blues are rumoured to have agreed personal terms with the Germany international last week after agreeing to trigger his €60m (£53.8m) release clause.
Werner has played a part in 33 Bundesliga goals this term - no player has been directly involved in more - and is believed to have been high on Liverpool's transfer wishlist.
Former Chelsea midfielder Ballack, who spent four years at Stamford Bridge, expects his compatriot's arrival to trigger the start of a spending spree for Frank Lampard's men.
"I think it's a good decision for both sides," he told Sky Sports Deutschland. "For Timo, because he fits there, because the way he plays football suits him.
"I think that, with Chelsea, he decided for a club where he has a better chance of playing, which is very important to him.
"The team will be rebuilt, it will certainly be strengthened and Chelsea will spend a lot of money to compete at the top again.
"A good young team is being built there, it is very promising. He [will be] playing together with even better players than in Leipzig."
Leicester City full-back Ben Chilwell, Bournemouth's Nathan Ake and Said Benrahma of Brentford are said to be Chelsea's three other targets for the summer window.
