Credit: SWNS <br /><br />Britain's oldest striker is still banging in the goals for his local football team three times a week - at the grand age of 90.<br /><br />Sprightly Mike Fisher - nicknamed Ninja by teammates - is still averaging a hattrick every game following a footballing career which began 75 years ago in 1949. <br /><br />The former RAF veteran turns out every Tuesday, Wednesday and Thursday for two local walking football teams after he started playing for them aged 82. <br /><br />Previously to that, granddad-of-two Mike, of Bloxwich, West Mids., played up until his 40s before taking a break from the beautiful game. <br /><br />After falling back in love with the sport in his 80s he now regularly appears for Old Corinthians, who play at non-league Rushall Olympic's ground in Walsall.
