Colchester United striker Clive Platt has admitted it was a big shock to hear of Paul Lambert's departure earlier this week.
Us boss Lambert opted to join League One rivals Norwich City on Tuesday, after less than a year in charge of Colchester.
Platt was shocked to hear of his departure but is now getting on with the job to try and keep the early season momentum going at the league leaders.
He told skysports.com: "He (Lambert) came in during last season and did a great job at the club, bringing some quality players into the club and laid the foundations of a good squad for this division.
"We've had a great start to the season, which was a downfall of ours last year.
"It was a big shock to everyone when we heard that Paul had left because none of us heard a thing about it.
"One minute we are top of the league, looking forward to a great season ahead of us and then the next our manager and captain (Dean Hammond) left within 24 hours of each other.
"Joe Dunne has took over the reins on a caretaker basis, which he has done before at the club, so we've just got to continue working hard and make sure that we continue to put points on the board for when the new manager comes in."
