You do not substitute Billy Sharp.
It is a Paul Dickov assertion that a player like Sharp should remain on the pitch until the end as his chances of grabbing a goal always remain high.
And he was proved right when Sharp popped up deep in injury time to secure the win for Rovers against ten-man Watford on Tuesday night.
“You keep Billy Sharp on the pitch,” Dickov told the Free Press. “He showed at Blackpool when he got his goal and he showed it again on Tuesday night, if he gets chances, nine out of ten times he will score.
“He just keeps getting in the right position at the right time.
“He will go through periods of the game without looking as if he is really affecting anything.
“It’s the one thing we’ve missed this year, someone to put the chances away. That’s what Billy does best.
“If he gets a chance and misses it he doesn’t get too down about it.
“He always believes he’s going to score. If you have that belief to score goals you’ve got a chance of getting them.”
The striker’s goal came after he drifted in and out of the game as well as missing two gilt-edged chances.
And Sharp himself admitted he breathed a sigh of relief when the ball finally hit the back of the net.
He said: “I was just relieved in the end.
“I should have scored before that but something inside of me told me I was going to get another chance.
“In the end we managed to win the game, which I felt we deserved.
“It is a good time to score when they can’t reply in the 93rd minute, but I am just chuffed we have got the three points as a team.”
Watford had striker Mathias Ranegie sent off after just 19 minutes for a senseless kick out at James Husband.
Chris Brown made the numbers advantage count five minutes later when his near post header put Rovers in front.
Watford looked to have snatched a point when Ikechi Anya slammed home on 68 minutes and the Hornets held off waves of Rovers pressure.
But Sharp struck late to seal Rovers’ first back-to-back wins of the season.
