Wednesday look destined to finish in mid-table and seemingly have little to play for, but Lees still thinks there is enough incentive to keep the squad motivated.
The former Leeds United defender says that Wednesday need to ensure that they finish in the top-half, otherwise this season could only be categorised as a 'massive disappointment'.
“We need to respond and not let ourselves down. We had a very good first half of the season and it would be a massive disappointment if we don’t finish in the top half.
“After we had gone round the fixtures once and seen what everyone had to offer, I thought we had a big chance to get in and around the play-offs and certainly top ten.
“Getting into the play-offs have gone but as a team, you must have targets and goals and ours is to finish in the top half.”
Lees has been a major reason that Wednesday still have a chance of claiming a top-half finish, as his performances at the heart of their defence have been hugely impressive.
He arrived on a free transfer from Leeds last summer and has shown his class in his first season at Hillsborough.
Wednesday have one of the best defensive records in the Championship and the 24-year-old centre-back's role in this cannot be understated.
Lees has been commanding and combative in his defensive work and has made very few errors throughout the season.
He will now be looking to maintain those standards, and if he can, Wednesday are well placed to achieve their objective.
At the moment, the Owls occupy 12th spot and if they can ensure that they remain in that position, then Lees will be pleased that the side have met his aim.
