Arsenal ace Theo Walcott has urged Jack Wilshere to be careful with his tweeting.
Wilshere has avoided FA punishment after a loose tweet about the refereeing for their 4-4 draw at Newcastle United.
"You have to be careful what you do in your personal life, but everybody's entitled to their own opinion," Walcott said, speaking as he prepared for the midweek trip to Denmark with England.
"I believe there's no point whingeing about referees after games - it's not going to change the result, you are only going to start digging holes for yourself - but again, everyone's entitled to their opinion."
Walcott added: "I don't tweet myself, I really don't have a clue what it's all about."
