Julen Lopetegui, Porto coach
It would be great to celebrate the club’s anniversary [Porto were formed on 28 September 1893] with a win against Chelsea. Their league position does not affect their matches in the Champions League – they won their first game 4-0. They are a great team with great potential and we need to play really well, to our limits, and be technically and tactically perfect.

I have great respect for Mourinho. He has been incredible in his career, very important to Porto because of his great achievements at domestic and European level. We are talking about a Chelsea team that has top players and a top coach. We are a team with a lot of hopes, ambitions and belief, but they will push us to our limits.

I just visited the museum before coming to the presser. The museum is absolutely amazing and when you are lucky to be a part of it it’s very emotional. You realise you did something important, it’s fulfilling. It turned my heart a bit softer so now I will go back to the hotel and get back in the mood again.
