SARACENS have made five changes to their starting line-up, all in the pack for tomorrow's (Saturday's) Heineken Cup trip to Viadana.

Expecting the Italians to field a much stronger side to the one that got steam-rolled at Vicarage Road last weekend, Alan Gaffney has named an all international front row of Kevin Yates, Matt Cairns and Cobus Visagie while Kris Chesney, Paul Gustard and Dave Seymour return to the fold.

Yates comes back in for Nick Lloyd and hooker Fabio Ongaro makes way for Cairns. Chesney comes into the second row alongside Vyvyan in place of the unavailable Chris Jack. Paul Gustard has recovered from injury to replace blind-side flanker Sakiusa Matadigo while Dave Seymour comes in for Richard Hill.

The backs line up the same with hat-trick hero Richard Haughton and Glen Jackson, who notched 26 points in the 71-7 thrashing, hoping to inflict more misery on Jim Love's side.

Saturday's landslide result was a tad surprising given that Viadana had given both Glasgow and Biarritz a scare in their two previous pool games, and Gaffney is taking nothing for granted when the sides clash again at the Stadio Luigi Zaffanella.

"We have got to win at the weekend, first and foremost," said Gaffney, putting any thought of an expected bonus point out of his mind. "Viadana will have a very different side to the one they put out last weekend, where a lot of their top players did not feature. They are preparing for a big league game against Calvisano the following weekend and will want to do well."

"We went to GRAN Parma last year and didn't play particularly well but got the bonus point win," he added. "Viadana are a better side than them so we are going to have to play to our abilities. The set piece should prevail - our scrum was a lot stronger than theirs but we expect them to toughen up in that department and we are prepared for that."

Gaffney revealed forwards coach Adrian Kennedy had spoken to Viadana coach Love after Saturday's ten try romp and discovered his humiliated players were so upset by the margin of defeat they organised a run at 6am on the Sunday morning, their preparations for the return clash starting in earnest.

It is that level of dedication and determination which underpins Sarries' Italian hooker Fabio Ongaro's belief his countrymen will be gunning for revenge tomorrow.

"We will find that they are a tough team over there because some of their players will be very disappointed about the game in Watford," said the 30-year-old international. "They want revenge and will put their first team out. They won't be thinking about the game the following week - they take each game as it comes."

Ongaro is now in his second season with the Men in Black since joining from Benetton Treviso, his first punctuated by Azzuri call ups and a neck injury sustained in the 2007 Six Nations, reducing him to just 13 appearances.

However, with Shane Byrne having retired in the summer Ongaro is in a tussle with Matt Cairns for the number two shirt while Andy Kyriacou continues to snap at their heels.

"It was a big jump for me when I first arrived," he added. "I found problems with the language and the life and then I was out injured for three or four months. But I have come back from the World Cup and am really enjoying it here. I am starting to play and physically I am better this year."
