The Blues have been the Jekkyl and Hyde side of the Premiership this season.
Packed full of talent, they are capable of beating anyone on their day but December sums up their inconsistency - they beat Manchester United, Liverpool and Newcastle but lost at home to Charlton and Southampton.
Boss Glenn describes that recent form as 'a little complacent' but expects nothing less than the Chelsea that should be good enough to challenge for the title to turn up at Stamford Bridge on Wednesday night.
Glenn said: "In recent weeks they've come unstuck and got a little complacent but I don't think this will be one of those games.
"I think they will be at their best and it will be a high-tempo game with a great atmosphere.
"It will be a atmospheric game and cool heads will be called upon. We have to maintain our focus on what we are trying to achieve.
"It's a big game, one we're up for and excited about. It will be an interesting two matches and whatever happens after this 90 minutes we'll just be sitting at half-time. The lads are looking forward to it, I know that."
Look out for more from Glenn tomorrow.
Glenn Hoddle expects Chelsea to be at their very best for Wednesday's Worthington Cup semi-final first leg.
