Sheffield United boss Neil Warnock has lashed out at Sir Alex Ferguson and Rafael Benitez for the teams they put against his side's relegation rivals.
Sheffield Utd boss Neil Warnock was left bitter after relegation
The Blades were relegated after a 2-1 defeat by Wigan but Warnock was angry at the Liverpool side Benitez fielded in a 1-0 loss at Fulham on 5 May.
He also felt West Ham beat a weakened Manchester United 1-0 on Sunday.
He said: "What goes around comes around and maybe Chelsea will win the FA Cup and AC Milan the Champions League."
Warnock was making reference to United's game against Chelsea in the FA Cup final this Saturday and Liverpool's match against AC Milan in the Champions League final on 23 May.
United had already won the Premiership title when they played the Hammers, who needed at least a point at Old Trafford to guarantee survival.
It's the worst feeling of my career because it would have been my greatest achievement to keep us up
Meanwhile, Liverpool's concentration in recent weeks appears to have been solely on the Champions League and Fulham secured their Premiership status by beating the Reds.
"I was disappointed at United's team," added Warnock. "You would have hoped and thought that, last game of the season, Cristiano Ronaldo, Nemanja Vidic and probably two or three more might have played.
"I think Sir Alex sold me a dummy in midweek when he said he would field a strong team.
"He has his own reasons, though. Maybe the FA Cup final next week is more important to him.
"At least I knew the players that were playing. I didn't even know two of those that played for Liverpool at Fulham last week.
"I'd never heard of them but when you are a foreign manager like Rafa Benitez, you probably don't give two hoots about what Sheffield United think.
"It's a long journey to Fulham, so the players are probably better off at home with their feet up.
It's the worst feeling of my career
"You are bound to feel bitter about the circumstances in our relegation but it's not going to get us back in the Premiership.
"You just have to get over the bitterness and move on but it's difficult at the moment. Fate is fate, though. Life is like that."
The Blades had a late chance to equalise against 10-man Wigan but Danny Webber hit the post when one-on-one with keeper Mike Pollitt.
"It's a gut-wrenching and horrible feeling for all of us at the club," stated Warnock.
"It's the worst feeling of my career because it would have been my greatest achievement to keep us up.
"All season we haven't made it difficult enough for other teams and have given goals away when we have been in good positions.
"Wigan haven't had to work hard for either goal and we've committed suicide really. The lads have been magnificent and tried their hardest and I couldn't have got much more out of them.
"But it's still very disappointing when you go down because of the thickness of a post."
Warnock refused to be drawn on his own future amid claims that contract talks had broken down.
He stated: "I don't want to talk about myself. It's a time for the club to look at what has gone on and then think about me later."
