The Argentina international arrives at Stamford Bridge until the end of the season after AC Milan agreed to end his loan stay at the San Siro, but missed the registration deadline to make his debut against Tottenham on Thursday in the EFL Cup.
Higuain’s arrival on what is initially a loan deal also means that Chelsea forward Alvaro Morata will be able to secure his loan move back to his first club, Atletico Madrid, although the Spanish club first need to offload Nikola Kalinic or Gelson Martins to meet Financial Fair Play rules.
Higuain, 31, scored 55 goals in 105 appearances for parent club Juventus having previously broken Serie A goal scoring records with Napoli, becoming the first player to score 36 top flight goals in Italian football history.
Chelsea hope the arrival of a striker with his pedigree will address their persistent woes up front.
The Blues have scored 40 goals in 23 Premier League matches this season – the lowest return among clubs in the top six. Morata and Olivier Giroud have contributed just six of those with much of the goal scoring burden falling on Eden Hazard.
Maurizio Sarri, who worked with Higuain for one season in Italy and pushed for his signing in the summer, has used Hazard as a false nine in recent times rather than using Morata to lead his attack.
Higuain will be eligible to make his Blues debut in the EFL Cup semi-final second leg clash against Tottenham on Thursday. Chelsea trail at the half-way point in that tie by one goal.
