Harlequins forward Mark Lambert does not believe the English salary cap should be an excuse for defeats in European competition.
He told BBC London 94.9: "It does have an impact to a certain extent, in terms of depth of squads.
"But it's very easy to see it as a knee-jerk reaction to one season."
The 27-year-old added: "If it's something that continues for three or four years it might become a more obvious issue.
"But I think there is a huge amount of strength in English rugby.
"There are English clubs that have had big results in Europe this season. I wouldn't be at all surprised if, this time next year, there are a few teams involved in the late stages of European competitions."
The salary cap for clubs in the Aviva Premiership currently stands at £4m, and Lambert believes that keeping that figure is an important step to maintaining an even playing field in domestic competition.
"I'm not a money man but I think given the economic situation of a lot of teams, you need some regulation," the prop continued.
"If it's a free-for-all, you wouldn't see the competitive nature of the Premiership as it has been in the last few years.
"You'd begin to see a gulf between those who have the money and those who don't."
