No team news yet for the games in the main competition, but teams for tomorrows game between Gloucester and Newcastle are out. I'm not a regular watcher of the English league, so can't make that informed a call. General context is that winning this competition gets automatic entry into Europe (otherwise restricted to the top 6 in the league). Top 4 in the league make playoffs. Gloucester are currently in 6th with Newcastle in 4th, with only 7 points separating 3rd from 7th in the league (6 points between 2nd and 3rd, and 8 points between 7th and 8th. So competition is hot. Making the league playoffs would be seen as a bigger prize for both, and I assume it is on that basis that the bookies are favouring Gloucester heavily. All games are at 'neutral' (but in the country of the first listed team) venues. Both sides have tough run-ins, so I suspect focus won't be so strong. In these circumstances team selection will tell a lot (if you know who is normally picked - but I don't! LOL) the the first few minutes normally dictates the match result.
I've no inkling with regard to the other game, but can say that Cardiff are on a fantastic run of form, and their thrashing of Embra in the QF suggests they are targeting silverware. The -4 seems like very tasty, especially as Pau are locked in a battle to make top 6 in their league (which is playoffs AND Europe)
In the Leinster game there are a few injury concerns for Leinster, which suggests that they may be slightly off full strength in some key areas, and probably particularly in impact off the bench. Most worrying is scrum-half McGrath, who if he isn't fit means other changes (due to restriction on overseas players). Conflicting reports about whether he'll make it, but latest ones suggesting he definitely won't. I'd still expect Leinsters tight 5 and big game experience to kick in, but the -11.5 seems too big an ask to me, especially with the injury concerns. Scarlets came to Dublin twice last year in the league finals and beat both Leinster and Munster, so they won't have any fear.
Racing Munster is harder to call. Rumours that Zebo may drop to the bench seem strange to me. Munster this year remind me very much of the 06 vintage. Good players in most positions and excellent players in some, but by comparison to the best teams, they overperform in big games, hanging in and winning games against teams of (on paper) perhaps better players on aggregate. Racing impressed in winning away to Clermont, albeit with help from some very dodgy refereeing (although Munster got their rub of the green too!). Racing have yet to close the deal and while Munster haven't won a big trophy with many/any of these players they do have the grand slam heroics and memories of some key players. 30 degree weather in the south of France is an ask for both teams, but I think Munster can do it, or at least make it into a nailbiter decided by a point or two. Munster +4 seems sensible
