Are Villa 'stale and predictable'?

Nine of Unai Emery's starting XI against Sunderland were players he inherited when he walked through the door at Aston Villa almost three years ago. Only Morgan Rogers and Evann Guessand have been added since - and had Youri Tielemans been fit (an Emery transfer), even Guessand would likely have been on the bench. It raises an awkward question: why, after six transfer windows, does Villa still look so much like the team Emery found waiting for him?
