The battle for the skies will go a long way to deciding the war for vital Guinness Premiership points at Vicarage Road on Sunday, as two of the best locks in the division fight it out.
While Worcester's Craig Gillies has dominated domestic airways in recent seasons, Saracens' Chris Jack has reigned supreme in the international arena and Mike Ruddock maintains the All Black legend will have to be shot down if the Warriors' embryonic recovery is to continue.
The Worcester director of rugby takes his team to the home of one of the top flight's inform teams this weekend, looking to break Saracens' three-match winning streak and extend their own to four.
But to do that, they will have to neutralise a player who has not only adjusted well to northern hemisphere rugby but has already established himself as one of the outstanding front-five forwards in the competition.
Ruddock has promised his team will not be cowed by Jack's reputation [they have a New Zealand international of their own] and says that, in Gillies, they have the perfect man to negate Jack's impact.
"That will be a good contest," Ruddock conceded. "Greg Rawlinson, for us, cancels out the All Black factor, if you like but if Craig plays anywhere like he did against Bristol, then we will back ourselves to win that contest in the lineout."
Gillies, who signed a new three-year contract earlier this week, was back to his best against Bristol and his mastery of a lineout that stole umpteen throws was the key factor in Worcester's first league win of the season.
But Ruddock knows Jack and Saracens, who are fourth in the table and in the quarter-finals of the Heineken Cup, will be rather more demanding.
"What has impressed me about Jack is the stuff he has done away from the set-piece. He has scored two tries in a game recently [in the 45-16 defeat of Biarritz in the Heineken Cup] and has been very good," he said.
"Obviously, there is a match-up to be won in the lineout but we will have to find a way of cancelling him out in the other areas of the pitch because his contribution has been fantastic.
"If we let them play their game, they will tear us to pieces. The more you look at them, the more you realise how dangerous they are. They have a lot of mobility in the back row and their half-backs [Glen Jackson and Neil De Kock] are two of the stand-out guys in the league.
"We will have to try to disrupt the quality of the possession they get and, when we do get a chance, we have to show we can play."
Worcester's chances will not be helped by the continued absence of hookers Chris Fortey and Ben Gotting, who is out for the rest of the campaign.
Japan-bound Drew Hickey is also out with a hamstring injury and that will mean a recall for Tom Wood. Miles Benjamin has been brought back from England Under 20 duty to start on the left wing.
