Senna knows his Spain teammate is a target for both La Liga giants as he considers his future as Arsenal captain.
"I think the arrival of Cesc would be very good for us all, for the fans because he is a great player with great quality. Everyone would be happy for him to come to Spain and demonstrate the footballer he is," said Senna.
"I think Cesc is more connected Catalonia in Madrid, but Barcelona may not be his priority. It's all talk at the moment."
