Jose Mourinho  believes it would be "impossible" for Chelsea  to prise Zlatan Ibrahimovic  away from Ligue 1 leaders Paris Saint-Germain .The Sweden international has been in sensational form for PSG, most recently scoring a hat-trick in a 4-2 win over Toulouse on Sunday.Mourinho freely admits that he remains in contact with Ibrahimovic, whom he coached at Inter, but says there is little chance of a reunion at Stamford Bridge."Zlatan to Chelsea? It’s impossible," Mourinho told Canal Football Club. "He’s happy at Paris. I know because he is my friend and we are in touch. "PSG, with all its wealth, would never open the door. That’s mission impossible."However, Mourinho did suggest a move for Monaco striker Falcao could be a possibility in the future.He said: "I have a team, but no striker. Falcao does not have a team. A player like him can't play in front of 3,000 people. Monaco is a club to end [your career with]."The Stamford Bridge boss also ruled out the possibility of a swap deal involving Edinson Cavani and Eden Hazard."Eden is our boy," he added. "We want him to stay for 10 years. We want to build the team around him. He’s a player with the style of football that we want to have in our team."
