Pakistan bowler Saeed Ajmal has shrugged off fresh criticism of his bowling action after taking seven wickets against England on Tuesday.
Former England player Bob Willis had earlier made comments suggesting that Ajmal illegally bends his elbow during his bowling action.
Ajmal has defended his action on a number of occasions and chose to concentrate on his performance when quizzed on the comments.
The spinner said: "I am just concentrating on my bowling and it is basically up to the umpires and referees to say if there is a problem with my action.
"Does it trouble me that someone in England questions my action? It's no problem."
Ajmal had earlier recorded career-best figures of seven for 55.
