Having recently notched his 150th career league goal, Jermain's appearance in the 4-0 win at Villa Park marked the 400th in the league in his career.
His tally comprises 29 games for AFC Bournemouth, 93 for West Ham United, 31 for Portsmouth and now 247 in our colours.
He made his Football League debut for Bournemouth at Stoke City in a Second Division fixture on October 28, 2000, netting the visitors goal in a 1-2 defeat. His league goals tally stands at 151 plus 58 in 96 cup and other matches.
Having dominated the first half without reward, Jermain paved the way for our 4-0 win at Villa with the crucial opening goal in the 57th minute.
Gareth Bale then took over with a superb hat-trick as we moved back up to fourth in the Premier League.
"I thought we controlled the game in the first half, passed the ball well, showed great energy and it was just a matter of time before we scored the goals," said Jermain.
"I feel stronger than ever. I've always said it's fantastic when you are playing in a great team and I'm playing with great players. I'm delighted."
Every goal Jermain scores has a little extra significance as he continues to climb up the club's all-time top goalscorers list.
The goal at Villa moved him to within one of the great Alan Gilzean, who stands seventh on that list.
JD has scored 14 goals in all competitions this season to move him on to 132. He needs another seven to make it into the top five.
