Leicester City boss Nigel Pearson was delighted with victory over Southampton.

Riyad Mahrez enhanced his growing reputation by scoring both goals for Leicester.

Pearson insists spirit has never been a problem in his camp and is at a loss to explain the recent upturn in results.

"It has been a big factor in our change of fortune, but throughout the season it's been a big factor," said the Leicester boss, who this week was named manager of the month for April.

"From my own perspective of being in the dressing room, we've never lost hope of what we can achieve.

"It's been tough because when you look at the run we're on currently, which is pretty unthinkable really in the context of our season, we've needed to when you look at the results of the other teams who are down there with us.

"We've not been able to pull away and that might have had a negative affect, but it hasn't. And that is testament to our players.

"We need to keep showing it in the two remaining matches as they are against teams down there with us, battling against us. Against teams who also need the points.

"I don't know why it has changed for us. I don't know what the difference has been. We've played well for a long time but now we're keeping clean sheets and scoring more. It sound basic but it's hard to give a definitive answer.

"Our managing of the game during games has improved. That has come with the experience of playing in the Premier League. We didn't have that at the beginning of the season.

"But the margins are so small between a good performance that yields no points and a good performance that wins three points. I can think of a number of occasions this season when we've played exceptionally well and come away with nothing."
