Howson believes players need to be extra special to get noticed if they are playing for an unfashionable club such as Norwich and cites the case of striker Grant Holt who has been overlooked by England despite being one of the Premier League's top marksmen over the past 12 months.
Howson said: "You want to play consistently because if you are doing that the team is succeeding. But if you look at Grant Holt he has been very unfortunate. He had a terrific season last season and still didn't get the call-up which he deserved.
"He was the second-highest English goal scorer behind Wayne Rooney and still didn't get a chance. What more does he have to do?
"They may be looking at the bigger clubs. If you are playing for the bigger teams maybe you do have a better chance. I'm not just thinking about Norwich but some of the lads at say Swansea have been playing great and still not got a chance.
"I don't pick the team and can't do anything about it although it's something that is not impossible as John Ruddy has shown."
