Manchester United legend Andy Cole says Javier Hernandez must get better at beating the offside trap.

The Mexican is blessed with blistering pace, but too often falls victim to the linesman's flag.

"When you are anxious to score goals again and impress you tend to make your runs too early," Cole told the Manchester Evening News.

"When you are on the shoulder of the defender and have his speed you just have to hang back and make your runs slightly deeper and bend the run.

"That will come as he works his way through the challenge. He will get there because he is quality just like Ole was. The good thing for him is that he'll get the games. The manager is trying formations, like the diamond, and is so good at ensuring his squad get enough matches.

"Once you get those opportunities you have to take it and make sure all the hard work pays dividends. As much as the manager will rotate you also find if you score goals for Sir Alex Ferguson then you will stay in the team. He's not going to ignore that as Chicharito found to his advantage in his first season."
