Aston Villa manager Martin O'Neill is confident that striker Gabriel Agbonlahor will continue to improve in the coming seasons and become a prolific goalscorer.
The 23-year-old has netted 14 times for Villa this season and O'Neill believes that there is much more to come from the England international.
He told reporters: "Gabby has obviously improved since he was a kid and first came into the Villa side. He has got stronger for a start and his technique is improving.
"When you get to the 22-23 age bracket, you would think that players would maybe not be able to improve their technique any more. But I think you only have to look at Wayne Rooney.
"He has said he has started practising heading goals to make himself the complete player and I think there are lessons to be learnt.
"He has got plenty of things in his career to look forward to. I think he is capable of getting 20 goals, I wouldn't put it past him. Sometimes, you can learn the knack of scoring what you would consider tap-in goals.
"Little rebounds off keepers, once you have added two or three of those a season to your list of goals, gives you the confidence from being in the six-yard box and being comfortable inside the six-yard box."
