Arsenal goalkeeper Wojciech Szczesny has apologised for saying in a Twitter message that team-mate Aaron Ramsey looked "like a sheep shagger".
The 21-year-old Polish goalkeeper has been reminded by the club of his responsibilities, and apologised for any offence his remarks had caused.
The statements mocking Wales captain Ramsey have since been deleted from Szczesny's Twitter timeline.
"I'm sorry if anyone was offended by my tweets," Szczesny wrote on Twitter.
"There are some things we should not joke about and I have crossed the line. Sorry!"
Ramsey, also 21, had posted a picture of himself attending a golf event, to which Szczesny responded: "I don't wanna be rude mate but you look like a sheep shagger on that picture."
A club insider told the spoof "Normally we are used to the ball crossing the line with Wojjy in goal, today he crossed it himself"
