Baby Bok ready to lead Exiles to glory
The South African back row forward, who captained the Exiles in a 20-26 loss European Challenge Cup loss to Stade Français the past weekend, believes his side must be clinical against a well-organised Warriors outfit.
"The Premiership is an incredibly tough competition, so when we get ourselves into good field position, it's important that we make the most of those opportunities," said De Chaves, 27.
"Our work ethic has never been questioned this season and we know that if we get everything right and we play to the best of our ability, we will win."
De Chaves, the recipient of the Players' Player of the Year award last term, was a shining light for the Exiles during their narrow 26-20 defeat against Stade.
Looking to build on the positives from last Saturday's game, the former South African Under-20 player said: "There were a lot of good things to come out of the Stade game and we pitched up at training on Monday in a positive mindset ready to go.
"The team really stepped up against Stade and our physicality, defence and attack were good. We just need to finetune certain aspects of our game and the results will follow."
Irish take on a Worcester side, who themselves were edged out by French opposition in their previous outing. Warriors were defeated 27-20 by Oyonnax, but come into this game having won two out of their last three league games.
"Worcester is an excellent team with threats across the park and we'll need to' be at it right from the word go," said De Chaves.
"There promises to be a fantastic atmosphere at Sixways on Friday and I believe there are many London Irish supporters making the trip.
"We'll be doing everything that we can to come away with a win and we're all looking forward to the game."
