Well this throws a spanner in the works..
Can't help but think Capoue's move from 15 to 29 is done just to free up the more desirable number 15 as he knows he's leaving the club, Just like Scott Parker's change from 8 to 6 before his sale for Paulinho. The idea that he's taking it because it's his favourite doesn't really fly with me since the number was free last season when he signed. Jake Livermore had 29 last but left on loan to Hull the day before Capoue signed and later took the number 15 shirt if Wikipedia serves me correctly.
Chadli's move seems trivial although it's probably a preference thing. Eric Dier to 15 makes sense but it would really frustrate me if, like Lamela and Chiriches last season, he wears this number in Europe but another, like 25, in the league. Hopefully not. Young Ben sticking with 33 until Rose leaves and free's up 3 I guess.
