Lewis Moody says Leicester Tigers will be fuelled by anger as they prepare for Sunday's Guinness Premiership semi-final showdown with Bath at Welford Road.

The open-side flanker said the whole squad were bitterly disappointed when they lost their 31-game unbeaten home record to Saracens on Saturday.

Tigers were well below par in the 32-23 defeat and Moody says they will have fire in their bellies in training this week and are determined to put things right.

"We will sit down, evaluate our performance and the mistakes that we made," said the 31-year-old England flanker.

"We were all guilty of them at one stage or another and that will anger us.

"That's the way it should be. We should be angry. When you lose and you lose at home in a game that you should win, it has to hurt.

"It was frustrating. They were a side we knew we could beat and it was very disappointing to lose that record.

"We will go through what we did and then forget about it and move on to the next game.

"We must take that disappointment in the right way and manifest it in a result on Sunday."

Moody says that, despite losing England flanker Tom Croft in the 66th minute to a yellow card, Tigers still had chances to win the game.

"Any team that comes to Welford Road is always up for it," he said.

"Saracens played well and took the opportunities that came their way.

"We still got ourselves in positions to score late on but we turned the ball over.

"It was a game that was there for the taking and we have to make sure that the disappointment from that defeat shows itself in the right manner this weekend."

Moody will make his final appearance at Welford Road against Bath – the team he is joining at the end of the season.

But the sepia-tinged spectacles will have to wait.

"It's just another game at Welford Road for me," he said. "It's a simple as that.

"It is a game we have to win to progress into the semi-final and that's the only way I will be looking at it.

"The nostalgia and looking back will come when the season has finished. We have to make sure that we put in a performance."

Meanwhile The Rugby Union are investigating the behaviour of Saracens head coach Brendan Venter at Welford Road on Saturday.

The South African was spoken to by stewards who rejected calls from fans in the Crumbie Stand for him to be ejected after several altercations with supporters.

Venter had been repeatedly asked to sit down by fans who had their views blocked during the game.

The Sarries head coach is on a season-long suspended ban for critical comments made in the wake of Leicester's win at Vicarage Road back in January.

An RFU statement said: "The Rugby Union has been alerted to incidents at the Leicester Tigers v Saracens match.

"We are awaiting a report from the match referee and any formal complaint from Leicester Tigers or their fans before considering what action, if any, should be taken."
