"according to reports".
That's basically admitting "we have absolutely zero sources within the club anymore, and therefore have to rely on repeating what other websites / newspapers have already said over the last few days".
I agree. Also, OndaCeroMalaga have less than 10k followers on twitter and are just a radio station who possibly decided to make up the 'option to leave after one year' stuff based on Atletico Madrid speculation. That's also being repeated by the echo and other sources now.
Sandro has #probably# agreed to join but various issues are being blamed, image rights stuff, then Malaga making things hard and wanting more than €6m. Probably all made-up.
