These two sides get their pre-season underway in earnest with their first game in the International Champions Cup in Michigan.
Juventus and Tottenham Hotspur are the other two sides in this group ensuring it should be a competitive way for the clubs to prepare for the forthcoming season.
In the transfer market, Roma have looked to strengthen defensively and offensively as the Giallorossi look to mount a title push against the all-conquering Bianconeri. However, the capital club have lost Mohamed Salah to Liverpool and his goals, coupled with those of Serie top scorer Edin Dzeko, were vital to their second place finish last term.
PSG have been quiet so far in the summer transfer window although the French giants have been linked with some big names. Unai Emery has, however, brought in Dani Alves in a shrewd bit of business and the Ligue 1 side are favorites for the game against Roma.
bet365 offer a win for the Parisian outift at 9/10 (1.90) while Roma under new manager Eusebio Di Francesco can be backed at 13/5 (3.60) with the draw priced at 11/4 (3.75) .
Roma could generally be relied upon for goals last season, and in a thrilling end to the campaign, their last six Serie A games produced 32 goals. Both teams to score paid out in eight of their last 10 league fixtures and against PSG the temptation is to back goals at both ends once more.
However, backing neither side to keep a clean sheet is offered at just 8/15 (1.53) which will probably only appeal as part of an accumulator bet.
More attractive, however, is the price of 5/6 (1.83) for both teams to score, with over 2.5 goals in the match. This bet paid out last summer in both the friendlies where Roma faced quality opposition in Liverpool and Argentine giants San Lorenzo.
Meanwhile, this bet has paid out in four of the seven matches that PSG have contested in the ICC and looks a solid option for this week's clash.
