Manchester City right-back Kyle Walker has taken to Twitter for the first time since getting sent off on his home debut for the club.The 27-year-old joined the two-time Premier League champions from Tottenham Hotspur earlier this summer, and impressed in his first outing.Walker picked up BT Sport's Man-of-the-Match award for his performance in City's 2-0 victory over Brighton on the opening weekend of the season.It was a complete contrast on Monday night, though, when the England international was given his marching orders before the half-time break in a 1-1 draw with Everton.Referee Bobby Madley issued Walker with two yellow cards inside three minutes; the first of which was brandished for a foul on Leighton Baines.The second was a contentious one as it was deemed that he deliberately shoved Dominic Calvert-Lewin while waiting for the ball to drop.Manager Pep Guardiola remonstrated with fourth official Michael Oliver when the red card was shown, and the Spaniard refused to discuss the decision with reporters after the match.Walker has spoken out, though, and has opted to apologise.
