That would have meant glory in the Euros would have given him a clean sweep of ranking titles in 13 months.
He said: âIf I do (win the Euros), Iâll be devastated as I missed two darts at the UK Open and that would be all of the ranking majors done in my career.
âI of course will be really up for winning this one. Iâm going to take it one step at a time.
âIâm not defending anything. Everything Iâve won, Iâve won them titles. Iâm only trying to retain.
Itâs going to be incredibly hard to win like I did last year. I didnât retain the Grand Prix. But if I win this one, whoâs to say I canât go on a good run at the Slam, Players and Worlds.
âBut you have to understand that youâre not going to win everything. Iâm just going to try my best.â
Humphries smashed Nathan Aspinall 6-1 in his opening Euros clash.
He added: âI felt it was a really good game. I felt my scoring was really good. I hit a lot of 180s, I think Nathan hit a lot of 180s.
He was really consistent, I think doubles in a couple of legs let him down. But the 122, the 152 they were just massive shots that turned the game around for me and itâs something I can do. He felt like he did last week when he played Luke (Littler), he didnât really do much wrong.
âI donât think I was unplayable there. I think if Nathan wouldâve hit his doubles when he had his chance it couldâve been 4-4 even though he was playing really good.
