Alex has not been able to play for Chelsea due to his lack of caps for the Brazilian national team. Work permit rules in England requires that a non-
EU player must have played in 75% of his country's international games in the last two years. Until this is resolved, Alex's stay at PSV seems likely. PSV Eindhoven are currently looking for an option to sign the defender from Chelsea.
What kind of a dumb rule is this. If a top football club like Chelsea wants to sign a player like this, they should be allowed to without these sort of beuracratic problems. Anyways, Shev shouldn't have gone out to the media and talked of how he would like to play for an MLS side some day, specially now of all times.
