Richard Keogh has hailed the Lampard effect at Derby County and believes the arrival of the former Chelsea midfielder at Pride Park has been good for his game.
The Rams are eighth in the Championship after a mixed start to the campaign but their performance at Old Trafford last month turned heads, as the underdogs dumped Jose Mourinho's men out of the Carabo Cup on penalties.
Keogh was part of a terrific performance - he buried a spot-kick in the shootout too - and the Republic of Ireland defender said that set the bar for his team-mates and his new manager.
"He's been good for myself, obviously," Keogh said of Lampard, who took the reins in the summer.
"He's a young manager coming through and the gaffer [Martin O'Neill] can speak for how hard it can be for a first-time manager to come into a club.
"But so far he has come in and really done well with us. He has set his own standard in what he expects of us, and we've been ticking over quite nicely.
"Obviously we'd like a few more points on the board, we probably deserve that, we've lost a few games that we shouldn't have lost.
"But the Man United performance shows the kind of level that we can get to if we play to it."
Tonight Keogh's focus is on helping Ireland pick up a much-needed Nations League win against Wales at the Aviva Stadium.
He lined up in a defensive three alongside Shane Duffy and Kevin Long on Saturday night, shutting out Denmark in a goalless draw.
O'Neill changed things up with a 3-5-1-1 system that, while admitting it will take some getting used to, Keogh relished.
"I really enjoy the system. Obviously, I spoke to the manager about it before and I'm quite comfortable going out to the right-back area and defending one v one.
"I've done that throughout my career and yeah, like I say, our strength as a back three is defending the box.
"Hopefully, I'd like to think, on the ball we can offer something as well and give it to the more creative players.
"I think we are still possibly learning the system, to get it to exactly how we want, but with the last two performances we have shown we are moving in the right direction.
"I think the manager has touched on this before in previous games.
"We have a short period, meeting up together, and there is not overly a lot of time for the manager to get exactly what the manager and the coaching staff want [across].
"But as a general idea there is a lot of information coming to us and as players we have been taking that on-board and making sure we put it into practice.
"I think, as the manager said, a big strength of ours in that togetherness as a group. It really comes to the fore at times when we need it.
"We need to make sure that we have that again on Tuesday and play attacking football and hopefully get a positive result."
