Gardner, 26, insists there has never been a problem with the playersâ€™ work ethic.
He said: â€œThereâ€™s been people talking and chatting about this, but itâ€™s a load of rubbish. The gafferâ€™s come in and itâ€™s the same. Every football club has to work hard.
â€œWeâ€™re working hard â€” we have to if we want to stay in the Premier League.
â€œWe work hard every day. No matter what manager comes in, weâ€™re professional footballers.
â€œI donâ€™t know where this has come from, that Paolo Di Canio will work us harder, because at any club, thereâ€™s only one place youâ€™ll be found out, and thatâ€™s on the pitch."
