Celtic striker Leigh Griffiths celebrates his winning goal at Motherwell Strikers need to score goals for themselves, for the pressure of it. Playing for Celtic you get a lot of chances and sometimes that can play on your mind when you are not scoring, said McManus, who made over 150 appearances for Celtic between 2003-2010.But the most important thing is he still in there, and hes going to be a big, big player for Celtic at the weekend.Leigh Griffiths has had a tremendous season. Its not easy scoring goals at the Old Firm, certainly not Celtic. You need to be the right type of character to handle the pressure, to relish the pressure that comes with it, and Leigh has certainly done that.He will now be looking to advance on his next aim, to become a regular for Scotland. But he has had a terrific season and when you have someone like him in your side you know you are going to get chances and you know you will get an opportunity to score goals.
