David Luiz has been handed the number 30 shirt for his second spell with Chelsea.
The Brazilian international completed a return to Stamford Bridge on transfer deadline day, with the Blues paying Paris Saint-Germain £32m to re-sign the centre-back.
Luiz wore the number four shirt, which now belongs to Cesc Fabregas, during his first spell at Chelsea, but has been handed the number 30 for the 2016-17 campaign, while fellow deadline-day arrival Marcos Alonso has taken the number three shirt.
Luiz, 29, initially represented Chelsea between 2011 and 2014 before making the move to PSG, where he won nine trophies.
