TEAM news is vital when betting on tonight's Europa League matches. I've gathered some info and anyone who has pointers about other ties should post here.
So let's start with Swansea and Spurs.Swansea coach Garry Monk will be without injured midfielder Jonjo Shelvey at Napoli. He joins Michu on the sidelines with the Spanish forward recovering from ankle surgery.
Provisional squad: Vorm, Amat, Taylor, Flores, Williams, Britton, Bony, Hernandez, Dyer, Cornell, Lamah, Routledge, Tiendalli, De Guzman, Canas, Rangel, Pozuelo, Tremmel, Vazquez, Richards, Ngog, Emnes.
Napoli will be without goalkeeper Rafael, who tore the anterior cruciate ligament in his right knee against Swansea and underwent surgery this week in Brazil.
Jose Reina, who is on a season-long loan at Napoli from Liverpool, will deputise between the posts.
Tottenham may welcome back Sandro for the second leg of their Europa League last-32 tie against Dnipro. The 24-year-old Brazil midfielder has returned to full training, having been sidelined since suffering a calf injury in December.
Kyle Walker (hip) could also return but Spurs, who trail 1-0 from the first leg in Ukraine, will be without Etienne Capoue and Danny Rose after they picked up knee injuries in Sunday's defeat at Norwich.
Toronto FC-bound Jermain Defoe will bid goodbye on the pitch at half-time due to a hamstring injury.
Provisional squad: Lloris, Friedel, Gomes, Walker, Naughton, Dawson, Vertonghen, Fryers, Veljkovic, Dembele, Capoue, Onomah, Sandro, Lennon, Eriksen, Bentaleb, Paulinho, Chadli, Townsend, McAvoy, Sigurdsson, Adebayor, Soldado, Kane.
Eintracht Frankfurt will play in front of a sell-out crowd of 51,500 after staging a remarkable comeback to draw 2-2 at Porto last week. Frankfurt midfielder Sebastian Rode was this week ruled out for the rest of the season with cartilage damage to his knee and Porto remain favourites to qualify.
Lazio head coach Edy Reja has promised to take the game to Ludogorets as the Italians try to claw back a 1-0 home defeat.
The team from Razgrad won all but one of their group-stage games, conceding only two goals in the process, and Lazio learned first hand that keeper Vladislav Stoyanov can often be an immovable object.
Reja expects Italy keeper Federico Marchetti to be fit following injury, meaning Etrit Berisha drops to the bench, but defenders Andre Dias and Abdoulay Konko are sidelined. Lazio's star players – who include Miroslav Klose, Lucas Biglia and Antonio Candreva – are all expected to play some part.
Red Bull Salzburg coach Roger Schmidt is determined to keep his players' motivation high for a tie it would be easy to assume is effectively already over and is prepared for an Ajax onslaught.
Salzburg have not lost at home since last May and have scored 49 in 12 games – including three in Amsterdam.
