It may only be Round Two of the new Aviva Premiership season, but Worcester, London Irish, Sale and Newcastle are all wary.
Two matches this weekend will see the four sides face off against each other - with Irish travelling to Worcester and Sale hosting Newcastle.
All four teams were widely predicted to struggle across the media before the season kicked off last weekend, and only Sale picked up a win in Round One after their surprise victory at Kingsholm.
Very few expected it. Steve Diamond's squad has hardly undergone a radical overhaul in the off-season, a change to recent years, meaning that the core group that spent the majority of last season at the bottom of the Aviva Premiership remained.
A touch of fortune from the TMO aside for their second try, Sale were dogged against Gloucester - dominating the set-piece and silencing a Kingsholm crowd who are rarely subdued.
Even when their lead was threatened having gone from leading 19-3 to only 19-16, Joe Ford had the composure to land an important drop-goal. Not all sides go to Gloucester and come away with a win. For Sale to do so so early in the season is an enormous boost to their confidence.
It was a win at Kingsholm that more or less turned London Irish's campaign around last season in their own fight against relegation.
The unenviable task of starting out the new season against Saracens ended in defeat as many expected, but there were positives for the Exiles to take away from Twickenham. They have threats in the back-three with Marland Yarde and Topsy Ojo, while their scrum for the most part was solid.
Where Irish struggled was, much like last season, in defence. Not all teams are as efficient as Saracens in attack, but Irish looked porous when backed up against their own line. For a team that conceded 601 points last season - for reference Saracens conceded the fewest with 339 - the omens are not good.
At least scoring points will not be a problem for the Exiles, something which Newcastle are yet to do this season.
Friday's night big debut back into the Aviva Premiership was more of a damp squib, as the Falcons were left scoreless and on the end of a 21-0 defeat to Bath.
Kingston Park is a notoriously difficult ground to visit and the typical conditions - swirling winds and relentless rain - should have played into Newcastle's hands. Instead they were well beaten upfront by the Bath pack, which prior to the start of the season had been criticised for lacking enough bite.
Those types of games, indeed all home matches, are the ones Newcastle unconditionally have to win.
Lofty expectations have already been made about their prospects given Dean Richards is at the helm, but based on Friday's performance along with seemingly a lack of firepower out wide, change has to come swiftly. There are also question marks over whether Phil Godman, a signing from London Scottish, is the man for the job at 10.
Which leaves Worcester. Their second-half showing against Leicester was encouraging and with the heavyweight centre pairing of Josh Matavesi and Ravai Fatiaki they have plenty of power up the middle.
The key for Worcester, if they are to finally break out of the bottom four in the league after too many seasons trying, is consistency.
Sixways has never quite been the fortress it should be, despite modifications and a dedicated support base, which makes games like this weekend's against London Irish all the more intriguing.
If Worcester are serious about climbing the league and competing in the Heineken Cup, then the Exiles fixture is a compulsory win. Irish can and will cause problems, although their away form last season was a disaster, but this is an acid test for Worcester's ambitions.
Sale on the other hand can ensure that they open up a healthy gap between themselves and the chasing pack after only two matches with a victory at home over Newcastle.
It might only be Round Two, but every win for these four teams is essential.
