George Evans has joined Derby County from Reading for an undisclosed fee.
The 23-year-old midfielder, who can also play at centre-back, came through the academy system at Manchester City under the tutelage of Patrick Vieira and is known to Lampard from the Rams boss's time at the Etihad Stadium.
He has since gone on to make his name at Reading where he played 67 games in all competitions, scoring four times, having previously had loan spells with Scunthorpe, Walsall and Crewe in League One. He also represented England in the under-17s World Cup in 2011.
And Lampard was thrilled to get his man ahead of the club's first fixture, ironically at Reading, on Friday night.
He told the club's official website: "George is a very good player and arrives here at a good age as well.
“I worked with him when I was at Manchester City - he was training with the first-team regularly at the time - and he impressed me with the way he played, as well as with his attitude. George has fantastic attributes and will of benefit to us both on and off the pitch.
“We need the correct balance in the team and have been fortunate to bring in some exciting attack-minded players this summer, but George will give us security in terms of his defensive nature. He’s very comfortable on the ball and can move it quickly, which is something that we are looking for.
“At 23 years of age, with Championship experience at Reading and the upbringing he had at Manchester City under his belt, I believe he is a great addition to our squad.”
