The midfielder was disappointed in their failure to deal with in form striker Jamie Vardy.
Ronald Koeman’s side should have been more than aware that their opponents would fight back having done it numerous times already this season, and Ward-Prowse admitted that they didn’t do enough to prevent Claudio Ranieri’s men from losing their belief.
“We were aware of it at half-time that they will come out the traps and cause us difficulties and unfortunately we didn’t rise to the challenge that was ahead,” Ward-Prowse told saintsfc.co.uk.
“The lack of concentration, I thought the goals were quite sloppy, I think they could have been avoided but we weren’t ready for it, even though we spoke about it at half time. It is one that you look back on and learn from.”
The 2-2 draw once again saw Jamie Vardy hitting the back of the net, as he scored both of the Foxes' goals to continue his fine form at the beginning of the season.
His brace took him to nine goals in nine games this season, making him the Premier League’s top scorer by some distance, while it was also the sixth consecutive game he has scored in.
And Ward-Prowse admits they couldn’t do anything to stop him as everything he hits goes in at present, saying he was disappointed at two dropped points.
“Anything he hits goes in,” said the England Under-21 skipper.
“He was a big threat that we needed to nullify and we were aware of that before the game, but he’s in good form at the minute. It is two points dropped. Having been 2-0 up, we have to learn from it and move on.”
