Chelsea have bolstered their defence with the signing of Brazil veteran Thiago Silva.
The 35-year-old left Paris Saint-Germain after Sunday night's Champions League final defeat to Bayern Munich and had already been offered to Frank Lampard's side.
Silva, who had interest from Fiorentina among other clubs across Europe and turns 36 next month, has signed a one-year deal with an option for one more but the lack of transfer fee has made him a worthwhile investment despite his age.
He joined PSG from AC Milan in 2012 and won 18 major trophies, including seven Ligue 1 titles, and has won 89 caps for Brazil.
Chelsea have already signed Ben Chilwell from Leicester City for about £55million, Timo Werner from RB Leipzig for £47.5million, Hakim Ziyech from Ajax £37million and young defender Xavier Mbuyamba from Barcelona.
A £90million deal with Bayer Leverkusen for Kai Havertz is close to being finalised with confirmation expected in the coming days.
They remain interested in a new goalkeeper after Lampard ran out of patience with Kepa Arrizabalaga.
Silva's arrival increases the likelihood of one centre back leaving, with Fikayo Tomori potentially being loaned out amid interest from Rennes and the club willing to listen to offers for Andreas Christensen.
Kurt Zouma and Antonio Rudiger seem less likely to depart unless a potential buyer offers a substantial financial package.
Chelsea struggled defensively throughout Lampard's first campaign as head coach, conceding 54 Premier League goals in addition to 16 in eight Champions League fixtures, and the club's record goalscorer questioned the mental strength of some players on more than once occasion.
