In an interview with RAC1, Guiu opened up about his move and his future, saying: "I don't regret leaving Barca. I left because I thought it was the best thing for my career, and now I have to enjoy the Premier League. It was a difficult decision; Barca gave me everything; it was my home. There were a lot of strikers, and I wasn't guaranteed a first-team contract, so I think I made the best choice. Maresca called me and told me she believed in me and the sporting project was incredible."
Speaking on why he chose to come back to Chelsea after just securing a loan move to Sunderland this summer, he said: "This summer we spoke with Chelsea because I wanted to get playing time. I arrived at Sunderland with great enthusiasm; the fans were incredible, some of the best I've ever seen. I was very comfortable, but after Liam Delap's injury, they asked me to come back. I'm a Chelsea player and that's where I'm going."
When asked about facing his old club Barca in the Champions League, the striker said: "It will be a special match, the match of my life. I hope I get some minutes. The key to Chelsea is unity and the coach's work. He works very well tactically, the training sessions are intense. He's certainly influenced by Guardiola; the training sessions are very similar to Barca's, with a lot of ball-playing and positional play. I've already told [Pau] Cubarsí that I'll be killing it, although I wouldn't celebrate a goal."
