The 25-year-old feels it does not make sense to stay with the Blues as he embarks on his seventh loan spell since joining the club eight years ago
Lucas Piazon says he is ready to leave Chelsea on a permanent basis because he is fed up with being sent on loan every year.
The attacking midfielder and winger joined the Blues from Sao Paulo in 2011 but he has made just three appearances for the senior side - all in 2012.
Since then, he has been loaned out to seven different clubs across five countries, seeing him spend time at Malaga, Vitesse, Eintracht Frankfurt, Reading, Fulham and Chievo before he was sent to Rio Ave earlier this month.
