Welcome to Deadly Duos, another original Bleacher Report series.
Deadly Duos takes an in-depth look at two players who form the core of the team and are true match-winners.
In the inaugural edition, we look at Manchester United's dream-team of Wayne Rooney and Cristiano Ronaldo.
Rooney and Ronaldo are synonymous with Manchester United and are well-known to millions of football enthusiasts around the world.
In the summer of 2003, Manchester United landed Cristiano Ronaldo from Sporting Lisbon in a deal worth £12m and Ronaldo has never looked back.
Wayne Rooney joined the Red Devils a year later in a deal worth around £31 million from Everton.
Cristiano Ronaldo is adored by the Old Trafford faithful for his dazzling skills, spontaneous footwork, and ability to score goals at regular intervals. In short, Ronaldo is a true "genius."
Spanish goal-keeper Santiago Canizares described him as "truly unstoppable."
We at DD agree with Canizares—Ronaldo's free-kicks are absolutely mesmerizing for keepers and fans alike.
It wouldn't be wrong to say that Ronaldo is a defender's nightmare. After all, he has humiliated, and caused sleepless nights for, many Premier League defenders over the years.
Last season, Ronaldo collected a staggering 42 goals, helping Manchester United retain the Premier League title and claim the UEFA Champions League crown.
Despite his potential to be the best and his recent win of the Ballon d'Or, Ronaldo, like everybody else, has his flaws.
He has been criticised for diving and his career, while it has been laden with honours, has also been laden with controversies.
The controversy scale reached its peak when, at the World Cup in Germany in 2006, his critics blasted him for playing a pivotal role in getting Wayne Rooney sent off and following it up by winking at the Portuguese bench.
His never-ending transfer controversy with Real Madrid shows no sign of an end with Real Madrid desperate to land the services of the Portuguese sensation.
Rooney is known to all United fans as a fiery character who loves to get into the face of the opponent. He's hardly ever in the good books of the referee, but despite this Wayne Rooney shows time and time again why is arguably England's best striker ever.
Rooney broke on to the Premier League scene with Merseyside club Everton and scored a match-winning goal against Arsenal at the age of 17.
Looking for a bigger challenge, he arrived at Old Trafford and slowly made his mark in Manchester.
The 23-year-old has a rather a bulky physique, which he uses to it's maximum effect in his game-play to get the better of the opposition.
Rooney's technique has won him much praise and his trademark volley against Newcastle stands out as arguably the best-ever goal in the Premier League's history.
He often falls into long goal-less droughts, but when on song, Rooney is truly unbeatable.
All in all, Wayne Rooney and Cristiano Ronaldo are what Manchester United is all about, United might not be a one-man team, but Rooney and Ronaldo are certainly the centre of attention at Old Trafford.
Be sure to keep an eye out for the next edition of Deadly Duos where we take an in-depth look at Aston Villa's duo of Gabriel Agbonlahor and Ashley Young.
