st. Johnstone vs Celtic prediction

In the Scottish league, St Johnstone vs Celtic. Good price for both teams to score here so I take it. The two teams have the best attack in the league with 35 and 41 goals respectively. Johnstone are 4th with 30 points. They don't have a strong defence but they are real good going forward. They have no clean sheet in their last 5 home games and have always had it hard stopping teams from scoring against them with both teams scoring in 16 of their 17 games. Celtic are top with 39 points. They really need to win here as they are neck tied with Aberdeen with just one point separating the two although celtic still has a game in hand. They are out of Europe so concentration is solely on domestic league and their domestic cup competition as they as they look to get back to the champions league next season. Both teams will score in this game. The host often enjoy free flowing football with goals and I don't see it stopping here. Celtic on the other hand might be the best defence in league but they have not kept a cleansheet in their last 3 away games. So I see both teams finding the back of the net of each other at least once today. GL!
