Trevoh Chalobah is the unbreakable man at Chelsea.
The 25-year-old centre-back has gone from the so-called 'bomb squad' - a group of nearly a dozen players exiled out of Enzo Maresca's first team - to being described as "the best solution" to shore up Chelsea's defence following an an emergency recall from Crystal Palace.
Loan spells being cut short in January are not unusual, but typically it is Premier League clubs bringing back their promising youngsters after cutting their teeth in the English Football League.
"We have new injuries," Maresca said on Friday before Chelsea's game against Wolverhampton Wanderers on Monday.
