In terms of them winning the title whereas the other top sides are shit*, yeah. But quality and "deserving" wise, I think it's different.
I do think they have been working well towards building a good side - both in terms of bringing through players and weeding out the rotten ones. Getting rewarded for the patience and faith they showed Arteta too.
Leicester weren't quality? Top 3 goalie, a really solid CB - albeit odd - pairing, the best DM in the world (Kante), a top 10 winger in the world in Mahrez and they had a striker who is probably one of the best stories in Premier League history lighting it up ...
They built that team perfectly - and were it not for the fact they lost Kante, they may have held it together a bit longer ... he was key to their success, as he was to Chelsea's and France's ...
The rotten ones included Xhaka, Saliba - which they kept ... key to their spine.
Fair point re: Arteta ... I wonder if he'll kick on after his big league win this year, or if the pressure will get to them. Unlike us, they will actually spend big money without selling.
