England captain Joe Root predicts there is a lot more to come from James Anderson after he became the most successful fast bowler in the history of Test cricket.
Anderson was made to wait until the final delivery of his 143rd test match but eventually took his wicket tally to 564 as he knocked back the middle stump of India tailender Mohammed Shami to clinch a 118-run victory for his side on Tuesday.
The 36-year-old Lancastrian had begun the day level on 563 with Australian great Glenn McGrath, having taken two wickets the previous evening at the end of a day in which his best friend Alastair Cook made an emotional farewell century.
He is now fourth on the all-time list behind a trio of spinners -- Muttiah Muralitharan (800), Shane Warne (708) and Anil Kumble (619).
"To achieve what Jimmy has achieved to date has been unbelievable, and the scary thing is he believes he's got a couple of years left," Root said at The Oval where England sealed a 4-1 series victory.
"In my opinion he's bowling the best he's ever been."
Anderson was given a standing ovation as he left the field alongside Cook, England's most-capped test player, record run scorer and century-maker.
They have been mainstays of the England side for more than a decade, playing key roles in four Ashes series wins.
Former skipper Cook, who announced his retirement from international cricket after the fourth test, described Anderson as a "freak".
"To see Jimmy pass Glenn McGrath's record was brilliant," Cook, who captained Anderson for 49 tests, said.
"We've lived in each other's pockets for 12 years and it's been a privilege to play with England's greatest cricketer.
"No disrespect to any other guys, his skills to do it time and time again, you almost take it for granted that's he's going to hit a length.
"I can't describe what he must go through, physically and mentally, to do what he does. He's a freak. It's been a pleasure standing at first slip for his bowling."
Anderson was close to tears after finishing the series as the leading wicket-taker with 24 in five tests.
"I'm trying not to cry," Anderson said.
"It's been a special achievement for me. It's not something I've aimed for. I've just enjoyed playing for England -- it's an amazing job."
Anderson said he wanted to keep going as long as possible.
"I feel pretty fresh considering how many overs I've bowled. I'm thoroughly enjoying playing," he said.
"As long as I keep my fitness in a good place, as long as I keeping enjoying turning up to practice and working on my skills, I'll keep going."
