Pablo Hernandez has identified his former Valencia room-mate Juan Mata as the man Swansea must stop if they are to see off Chelsea in the semi-finals of the Capital One Cup.
Swansea head to Stamford Bridge for Wednesday night's first leg seeking to reach a major Wembley final for the first time in their 100-year history. Club-record signing Hernandez, bought from Valencia for £5.55million, is likely to return to the starting line-up in London, along with top scorer Michu and Ashley Williams, after recovering from a thigh problem.
And if Swansea are to give themselves a chance of winning the tie, Hernandez knows just how crucial it will be to stop Chelsea's creative fulcrum. He said: "Mata is a big friend of mine. He was my room-mate at Valencia for two years. We used to eat lunch and dinner together too. He's a good player."
