Yahoo Sports reports: Sunderland sporting director Florent Ghisolfi says the summer transfer window will not be influenced by qualifying for the Europa League. The Black Cats made 15 signings in a "strange summer" last year in order to facilitate their move back up to the Premier League, but Ghisolfi says this year is about focusing on "low volume and more precision". "The most important [thing] will be to keep our foundations," Ghisolfi told BBC Radio Newcastle.
