It took the Bulgarian international just seven minutes to make his mark in a game crucial for both teams - Charlton had to win to have any chance of staving off relegation, we needed the points in our quest for European qualification.
Berbatov cleverly flicked Ledley King's pass around Talal El Karkouri and held off the defender before striding into the penalty area and sliding the ball past Scott Carson. It was his 22nd goal and our 100th in all competitions this season.
We were in control for the majority of the first half but Charlton - desperately clinging onto Premiership survival - fought back to create a couple of half-chances before the break, although Paul Robinson was never severely tested.
That remained the case in the second half as Charlton pumped the ball forward to the likes of Marcus and Darren Bent and, in the final quarter, Jimmy Floyd Hasselbaink, but Ledley King and Michael Dawson stood firm.
As you would expect, we had a number of breakaway chances but we didn't maximum advantage until injury time when Berbatov released Jermain Defoe through on goal and his 20-yarder looped over Carson and home, sending us into sixth place.
"The first goal was excellent, out of nothing and the second goal was out of nothing as well and we have the strikers capable of doing that," said Martin, who insisted there was 'more to come' from Berbatov. "I think he can score 20 goals in the Premiership," he continued, before looking at the game as a whole.
"Charlton is never an easy place to go so to come away with a 2-0 win, a clean sheet and three points is very pleasing.
"We'd won three of our last five away matches (and drawn one) so we were confident but you never know.
"Charlton were perhaps a bit unlucky not to score a goal but they played the long ball and Dawson and King were fine. It was just a matter of pulling the strings ourselves and we couldn't do that all the time, that was the problem. Everyone could see in the first half that we had more quality but you can punish yourselves if you give the ball away.
"Their supporters were right behind them and the only thing we could do was to try and silence them, but we couldn't. They wanted to stay positive and to show they had faith but for us, it was important to get the three points.
"We've had just one league defeat in 10 in the last couple of months, so that's very pleasing as well."
