David Wagner is not fooled by Leicester City’s promotion stumble as he prepares Norwich City for the ‘biggest test’ of their Championship season.

The Foxes have won one of the last six in the league to slip out of the automatic spots, after looking like champions-elect for most of the campaign.

Wagner remains convinced Leicester will be back in the Premier League next season – and is bidding to ensure his play-off surging Canaries join them ahead of Easter Monday's lunchtime duel.

“They have the best squad, the biggest budget. It's a proper Premier League side that plays in  the Championship. They have been on top, or near the top of the league, and they will get promoted, whatever the result against us,” said Wagner, with his side four points clear of their nearest top six challengers after beating Plymouth 2-1 on Good Friday. “We respect everyone on the highest possible level for sure, and especially Leicester, but it doesn't change how we approach a game.

"We look after ourselves, and I think this is one of the big steps this group has done in recent weeks and months and one of the reasons why the players play with this confidence, with this belief, with this freedom.

"This would be the biggest test of the season anyway, whether the momentum is for them or of us. That is irrelevant.”

Wagner expects Leicester to respond strongly after they slipped to a 1-0 Good Friday defeat at Bristol City.

“The truth is this can happen if you see the individuals in their squad. This is the best squad in the league by miles. This is the truth,” he said. “If you see recent results, maybe they are not in their favour, but if you look in a little bit more in detail, and see the expected goals or the statistics, I think they deserved not to lose one single game.

“What does it mean for us? Nothing. Because we will do it like we've done in the past. We started a long time ago to make ourselves independent from the opponent. Is it Plymouth at home? Is it Leicester away?

"Is it Rotherham at home and then Stoke away? Do they play three in the back line, four in the back line, whatever, five defenders. Is it raining, is it sunny? We had to make ourselves independent from all the circumstances we cannot affect and influence.”
