Stoke City manager Tony Pulis has asked his players to be careful whilst using social networking sites, according to Potters goalkeeper Asmir Begovic.
The Bosnia international, 24, posts regularly on Twitter.
Begovic told BBC Radio Stoke: "The manager's had a word with us regarding Twitter and all these other social networking sites.
"There's nothing wrong with it as long as you're sensible and do the right things. No one needs to be silly."
Begovic, who is followed by more than 8,000 people on Twitter, added: "It's all good fun, I like it because it's good interaction with fans and friends."
Meanwhile, former Stoke loanee Mark Crossley believes Pulis is well served with three quality goalkeepers at the Britannia Stadium.
Begovic is battling with Thomas Sorensen and Carlo Nash to be the Potters' first-choice keeper and started the 1-0 victory over Hajduk Split in the Europa League on Thursday.
Crossley, who was on loan at Stoke during the 2002/3 season, told BBC Radio Stoke: "Tony Pulis regards the goalkeeping position as a really important one.
"I really rate Begovic, I really rate Sorensen, and then he's got Carlo Nash as third-choice.
"The manager wants top-class keepers because he wants them to push each other."
