You're being ridiculous now.
1) Nobody is praising Martinez for the job of getting Swansea promoted, they're simply saying he had a hand in the way the club now operates on the pitch, which he clearly did. Laudrup himself even said that he's just continuing the footballing play style already employed at the club.
2) How can you possibly say that he 'couldn't' win games in the Championship ? Just because they didn't get promoted in their first season back in the Championship doesn't mean that he couldn't have got them to the Premier League himself had he stayed.
So now he's not only being praised for games someone else won, he's getting praised for games he didn't win but might have hypothetically won in another timeline?
