SWANSEA City have been dealt a double injury blow with Dutch duo Jonathan de Guzman and Dwight Tiendalli both out of Saturday's return trip to Old Trafford.
Midfielder de Guzman is nursing a calf problem, while Tiendalli has damaged a hamstring.
And though neither injury is thought to be serious, both will miss out when Swansea go back to Manchester United in the Premier League this weekend.
Swansea are already without Michel Vorm, Nathan Dyer, Roland Lamah, Pablo Hernandez and Michu.
And with de Guzman and Tiendalli now set to join the injured list, Michael Laudrup looks like having to call on a couple of Swansea's development players to fill the bench at United.
"Last weekend we had only 16 first-team players available so we had a couple of young players on the bench, and this weekend we may have three," said Swansea boss Laudrup.
"But as long as we can put out a competitive side, I am happy.
"And even if we are low on numbers, I think we will have that on Saturday."
