Tim Howard believes it is hard to impress as a keeper at Man United or Arsenal because their teams are so good.
The imposing American was brought to English football by the Red Devils, but a series of high-profile blunders led to him losing his place before being snapped up by Everton.
While the shot-stopper is now kept busy in a game, keepers for the league's bigger teams are often spectators and Howard believes this causes its own pressures.
"Playing at a club like Arsenal and Manchester United when you are in possession the majority of the time, it is difficult to stand out and be world class," said Howard.
"That is always the issue they have had with keepers down the years.
"You need a different mentality, It is difficult because the nature of the best is when you make a lot of saves you look a good goalkeeper.
"When the opportunities are few and far between, there is more pressure because you only get that one moment to shine."
