Cesc Fabregas is officially a Monaco player, with the transfer going through on Friday night following a week of hold-up.
Given Monaco's precarious position, and his ability and experience, Fabregas could go straight into the side.
"It is a great pleasure to join Monaco, it is a new project for me".
"I am looking forward to starting, we have a big game against Marseille on Sunday. I am very excited".
"There is no doubt Fabregas's place in the Chelsea history books is assured given his achievements over the past four-and-a-half seasons", a club statement read.More news: VLC Media Player Passes 3 Billion Downloads Mark, AirPlay Support Coming Soon
In what was the final season of his contract at Stamford Bridge, he had started only one Premier League match under new boss Maurizio Sarri.
Since joining the Blues from FC Barcelona in 2014, Fabregas has gone on to make 198 appearances while winning two Premier League titles and the FA Cup.
The 31-year-old has signed a three-and-a-half-year-deal with the principality club, with it hoped he will play a key role in helping the 2017 Ligue 1 champions avoid relegation.More news: Jerry Stiller in hospital after health scare
Fabregas will be required to make an immediate impact for Henry's men, who now languish second from bottom of the Ligue 1 table and face the threat of relegation.
Having enjoyed a glittering career, capped by winning the World Cup with Spain in 2010, Fabregas arrives at a club who were French champions just 18 months ago but are now in crisis.
