Swansea manager Garry Monk
Swansea boss Garry Monk on striker Bafetimbi Gomis: "He trains very well, his attitude is good and on top of that he is a good footballer and we need as many of those as possible in the team."
On today's game: "I think obviously being as Premier League team you have that tag as favourites but we have been the underdog for many years in cup competitions and we still have that mentality.
"Any time you suffer any defeat is bad but especially in the manner we did, it was very unlike us. The players have been itching to get back on track and this is our opportunity."
Swansea captain Ashley Williams catches up with his biog in the match programme before the match. Today's a day-off for the Welshman as he has a shoulder injury.
Edinburgh's win over Bordeaux last night means the Cardiff Blues - who are at Grenoble today - have already qualified for the European Challenge Cup quarter-finals.
