Carlos Tevez said: 'As for what happened on the bus, that was unfortunate and scary but it can happen anywhere.'

Brazilian midfielder Anderson added: 'A group of people was insulting to us and somebody launched a bottle.'

Chelsea have promised to carry out a full investigation and take the 'appropriate action' against those involved in the incident.

Anderson said: 'I think Chelsea are still a bit concerned with what happened last season.

'I believe that they still remember the Champions League final and as a result the game on Sunday was like no normal league match.

'It was a hard game that I watched from the bench but I think that the number of yellow cards we received was excessive.'
