The Ajax coach is being linked with Sherwood's job.
"What am I going to do? I'm not going to roll up and die, I'm just going to get on with my job, which is to try and prepare my team to win football matches and whatever will be will be," he said.
"I've just got to carry on with my business, show my personal pride and professionalism and make sure that those lads are prepared to win for the team and for the fans and for this great club.
"It's not only me, I've got two coaches with me, Les Ferdinand and Chris Ramsey, who have given a lot of time to this club over the years. I think possibly 30 years between us.
"It's a lot of time, a lot of effort and the club's been good to us in that time as well. What will happen at the end of the season, who knows?
"But one thing we can assure the club is that we've always been honest with them and we'll always give 100 per cent maximum to achieve what we need to achieve, whether that's in the development phase or now within the first team."
