Sporting Lisbon's Paim: Chelsea move most important step in career
"It is an unbelievable thing, a very important step, undoubtedly the greatest of my career."
Paim also told Maisfutebol: "At the end of the season, they have an option to buy and, of course, will be able to take a look at me. I will train and then we will see. I do not yet know where I will be in the team. That's up to the coach and the people who say I am going there."
