We are declaring it a Blue Day and to celebrate the occasion and show your support for the team, those at the Bridge can:

• Head to the Fan Zone at the Tea Bar for blue face painting, fun activities and live music.

• Pick up your Blue Day collectable patch to remember the afternoon by.

• If you are in the West Lower, join in making a mosaic by raising a card placed on your seat above your head as the teams walk out ahead of kick-off. Instructions will be outlined on the cards, and please do not swap cards with those around you.

• Look out for blue activities around the ground. Remember to bring your scarf and make sure to wave the flag on your seat to turn the Bridge into a sea of blue.

• Be in the stadium early for our full Blue Day-themed countdown to kick-off, featuring your favourite Blues anthems, our 'How blue are you?' crowd cam, and lots more to get the atmosphere rocking as we build up to the big match.

• Wear as much blue as possible. Our online store is a great place to start to make that happen.

In the words of the famous Chelsea anthem, ‘We're gonna make this a Blue Day’, so please join in the fun and we’ll see you at the Bridge for the derby!
