Over the years, Steven Gerrard and Manchester United have enjoyed what one might describe as a rocky relationship. The Liverpool legend has never been shy to voice his dislike of the Red Devils and vice versa with United fans are always quick to remind Gerrard of some his career failings.

Now, speaking on television with BT Sports, Gerrard has revealed how he reacted when he heard the news that United were to be signing Nemanja Matic from Chelsea.

For many, it seemed quite bizarre that Chelsea were so willing to let one of the integral members of their title-winning squad go to one of their main rivals and Gerrard has revealed he was just as surprised as anyone.

Discussing the impact the towering holding midfielder has had since arriving at Old Trafford Gerrard said: 

"[He's] One of the toughest opponents I've played against as a six," Gerrard told BT Sport. "He's very leggy, he's good in the air, he competes, he always gets a toe in, he can run and match your runs.

"He's very leggy, he's good in the air, he competes, he always gets a toe in, he can run and match your runs.

"He's very aggressive with the ball and without the ball, he can burst past you with it and he can catch you if you manage to stride past him on the odd occasion.

"Couldn't believe it [Chelsea had let him go]. I think out of all the Manchester United players I've seen them sign over the years he's the one, as a Liverpool fan, I thought 'Oh no. I hope not,' and then it happened."

United fans will love the fact that in the process of signing a world-class defensive midfielder, they managed to cause some angst in the life of one of their great rivals.

Matic made the move from London to Manchester for £40 million and has been simply immense for Jose Mourinho's side. 

The added stability in midfield has played a massive role in United's undefeated start to the season and Matic will be eager to kick on as the Red Devils look to reign in Pep Guardiola's rampant Manchester City.
