PSV Eindhoven impressed last weekend and the boss is anticipating more of the same.
He said: "Sporting will be technically good, will keep the ball and if it's as hot as it has been, it will suit them more than us.
"It's a test for us. We were at 50 per cent against PSV and they were at full steam, they are a good side and they proved it. We had to chase a lot although that was good for our fitness levels.
"I've got to think about certain things in this game. We've other things we'll look at, might experiment a little in midfield.
"It's unlikely we'll able to play the shape we've been working on so we'll have to change that as well, but these games are good for that.
"Result-wise it doesn't mean too much if we win, doesn't mean too much if we lose. We're striving to get our key players fit and once we do, I know we'll have a strong squad to pick from and we can do well this season."
Glenn Hoddle expects another tough test against technically gifted opposition when Sporting Lisbon arrive at the Lane on Sunday.
