Lampard has found communication under the 65-year-old to be a smooth process.
"Roy has been a breath of fresh air," he said.
"I know players will always wax lyrical about their current managers, that's just the nature of the beast. You can't expect them to say negatives.
"But I'm being honest talking about Roy. He's a gentleman, first and foremost.
"From the minute I first sat down with him at Chelsea when he came to meet a few of us there before the Euros, I found him a very personable bloke, very dedicated on the training ground, very driven, very pushed, very easy and friendly to talk to - in a good way.
"I have complete respect for him. With me, his communication has been fantastic."
