Charlton Athletic striker Tony Watt was praised by his manager Guy Luzon after he came off the bench to help the Addicks beat London rivals QPR at The Valley on Saturday.

Watt, 21, came on for Karlan Ahearne-Grant at half-time and scored for the Addicks seven minutes after he came on as they won 2-0 in their first game of the new campaign.

A famous career at just 21

Watt started his career at Airdrie United before making the move to Celtic for £80,000 during January 2011, scoring a famous goal in the Champions League against Barcelona. Watt then joined Belgian club Lierse on loan from Celtic in 2013 before transferring to fellow Belgians Standard Liège for a reported £1.2m fee last summer. He only spent five months in Belgium before he moved to England with Charlton Athletic.

During his time at Charlton so far he has scored five goals in 22 appearances and has established himself as a key figure in Charlton's starting eleven, forming a formidable partnership with fellow striker Igor Vetokele.

A reasonable scoring record

In his career so far his stats show as 114 appearances with 28 goals, and he seems to be becoming a player to watch for the future having been tipped for big things in the past. He was capped by Scotland at Under-21 level in the 2012-13 season and he made nine apperances, finding the net five times. He will be hoping to be capped by the full Scotland national team in future, but must begin to find the net more regularly in the Championship if he is to do so.

Charlton fans will be hoping that Watt will become a star in the future at The Valley rather than elsewhere, and that he'll be able to continue his goalscoring record at the club this season when they play Dagenham & Redbridge on Tuesday in the Capital One Cup.

Delight from Luzon

"Tony changed the game and brought us some bravery in the attack. He showed a lot of quality, and I am very happy for him," Luzon told the club's official website.

"He didn't start the game but I know that he has the quality to change the game. He accepted my decision [to start on the bench] - he had to.

"When the coach makes a decision that he thinks will benefit the team then he you have to accept it as a player, and he did. When he came on, he gave his maximum and helped us to win the game."
