What's your favourite treat?

Benfica manager Jose Mourinho was given a warm welcome by Chelsea fans after returning to Stamford Bridge on Tuesday.

The former Chelsea boss saw his new team take on the Blues at his previous club.

Despite the positive reception from the crowds who chanted his name loudly during the match, Mourinho was left disappointed following Benfica's Champions League 1-0 defeat.

An own goal from Richard Rios in the 18th minute was enough for Chelsea to secure the win.

Why was everyone talking about biscuits?

What's the snack you can't imagine life without?

Although he wasn't very pleased about the final result, Mourinho was all smiles after seeing his old colleague Brian Pullman during a press conference, giving him a big hug.

The Benfica manager asked Pullman, who retired from Chelsea last year after nearly six decades at the club, where his favourite biscuits were - his beloved custard creams!

"Where are my cookies?" Mourinho asked while embracing Pullman, giving him a kiss on the head after his former colleague pointed to them.

The pair removed some napkins on a nearby table, revealing a plate of the custard creams underneath.

Mourinho took a couple and then grabbed the rest as he stood up to leave.
