Swansea manager Francesco Guidolin is confident Borja Baston will justify his record fee and prove to represent good value for money.
Borja joined Swansea from Atletico Madrid in a £15.5 million deal on Thursday. The transfer fee for the 23-year-old Spanish striker exceeds the £12m Swansea paid for Wilfried Bony in 2013.
But Guidolin said he did not believe the fee will weigh heavily on Borja, who has signed a four-contract at the Liberty Stadium after scoring 18 goals in 36 LaLiga appearances on loan at Eibar.
"Borja is a young player, but I think he's very good," said Guidolin.
