Roy Keane has labelled for Leeds pair David Batty and Gary Speed as two of the toughest opponents he faced.
The former Manchester United captain led the club in an era of dominance and he was not one to turn down a physical battle in the middle of the pitch.
Throughout his Old Trafford career Keane came up against a host of tough opponents.
His rivalry with Patrick Vieira is well documented, but in his earlier days he was up against the likes of Speed and Batty.
Leeds had won the title in 1992, the year before the Premier League was introduced, and remained a top flight side for a further 12 years.
And Keane always knew he was up for a tough afternoon when they took on the Yorkshire side.
"The Premiership years ago, David Batty and these players, Rob Lee would always give you a hard game." he said.
"Gary Speed god rest his soul. These were brilliant players. Honestly, they'd give you a tough game.
"Gary Speed was a tough player to go up against, and, Gary was pretty nasty, y'know. Batty was nasty.
"I always felt these boys, people always remember me kicking people, a lot of these lads were kicking me - I was just retaliating over the years!"
Keane scored the winner the last time United beat Leeds in the Premier League back in 2003.
The two teams will renew rivalries this afternoon when Leeds travel to Old Trafford.
Ole Gunnar Solskjaer saw his side beat Yorkshire opposition on Thursday while the Whites put five past Newcastle.
United's home form is of stark contrast to their excellent away form and Marcelo Bielsa has fond memories of his last trip to Manchester.
The Leeds boss, then in charge of Athletic Bilbao, saw his side upset the odds and win 3-2.
