Sunderland boss Paolo di Canio stands by his massive squad overhaul this summer.
There are concerns that Di Canio has changed too much, too soon but he insists change was necessary after the decline of the club under old boss Martin O'Neill.
The former Swindon chief told the Daily Star: "Obviously we made a revolution. I wasn't worried at the beginning and now even less so because I've seen the lads working so hard.
"It takes a bit longer but I'm very happy. I'm not worried for the future.
"We're still in the middle of pre-season so you can't say the team is 100 per cent fit.
"But you're going to see straight away a team that plays together and tries to play football. It didn't happen last year.
"More importantly this team will be completely ready for the start of the season. When you change a lot it's difficult to think about a finishing place."
