I'd have taken that at the start of the draw. Donetsk, despite losing Fernandinho/Willian, have got a decent side that will be difficult to play on their ground. Leverkusen, intrigued by how they've evolved since 2002, and Sociedad are a new team but equally as intriguing and dangerous. Griezmann just one player that is good alongside with Vela, who played for Arsenal.
Arsenal, if they don't re-inforce their squad, could be in danger of not getting past the group stages. City should get through with Bayern and Celtic are out lol.
