London Wasps full-back Hugo Southwell knows that his high-flying side must retain their focus ahead of a critical period in the Aviva Premiership season.
The two-time Heineken Cup champions defeated capital rivals Harlequins on Saturday to move up to fourth place in the table.
Yet despite their lofty position Southwell is not taking anything for granted with games against Gloucester, London Irish and Worcester coming up.
"We have been working really hard as a squad so we feel we deserve to be there but if you look at the games we have left, you'd realise that we are going to have to keep working incredibly hard to stay there," he told the club's official website.
"After this weekend, we've got two difficult away matches at London Irish and Worcester and then we come back to some huge home games so the schedule is pretty tough.
"It is nice to be in the top four and hopefully we can stay there but we need to keep improving."
Gloucester themselves had an impressive result in round 14 of the campaign, toppling Northampton 27-11 on their travels.
The Cherry and Whites currently occupy fifth place and could leapfrog over Wasps with a home victory over their play-off rivals on Sunday.
"The Gloucester game this weekend is massive for both sides," Southwell added. "We are right next to each other in the table and both of us are coming into the weekend on the back of good away wins.
"We are obviously delighted to come back to training this week having got that win away at The Stoop, as we haven't won there in quite some time, but the mind has been focused pretty quickly today by the challenge we have on Sunday.
"We have to back that win up with a big performance at home."
