If David Luiz thought he could pick up exactly where he left off at Chelsea, he has already been given a surprise in the form of his shirt number.
The Brazilian centre-back rejoined the Blues from Paris Saint-Germain in a deadline day deal worth in the region of £34 million.
Jose Mourinho was at the helm when Luiz was sold to the French champions in 2014 but with Antonio Conte now in charge, Luiz has been given another chance to enjoy success at Stamford Bridge.
And Luiz wasn't the only last-minute addition to Conte's team as Spanish left-back Marcos Alonso also arrived from Fiorentina for £23 million earlier in the day.
However, it was Luiz's return which stole the majority of headlines on the final day for clubs to improve their squad and now it has been revealed which shirt number he will be wearing this season.
During his first spell in west London, the centre-back wore the No.4 jersey but that will not be the case this time around.
Cesc Fabregas joined from Barcelona the same summer Luiz left and subsequently took his squad number.
Following a busy day of deals, Chelsea have released an updated list of squad members and which shirts each player will be wearing.
In the list, Fabregas has kept his No.4 which has forced the Blues' latest signing to take the slightly less conventional No. 30.
Luiz wore No. 32 at his previous club and could have chosen that again, as well as 6, 9,16 and 17 which remain available.
We are not entirely sure why he went for No. 30, though. He does turn 30-years-old next April but it might be clutching at straws slightly to suggest there is any link between the two.
It would appear Chelsea fans are equally confused and surprised Luiz didn't take No.6. Here are some of the best tweets:
Meanwhile, Alonso has been given a more traditional defensive number of 3 even though he is widely expected to be backup to Cesar Azpilicueta at left-back this season.
