Michael Laudrup is delighted with Chico Flores' improving form ahead of Swansea's trip to Sunderland on Wednesday.
The centre-half was sent off for a head-high tackle on Louis Saha when Sunderland visited the Liberty Stadium at the start of September.
"Chico has calmed down," said the Dane, whose side have shut out Chelsea - twice - and Everton since the turn of the year. "He is tough, he wants to win the ball and he has adapted. He learnt a lot from that sending off.
"The players scoring goals get all the headlines, but over the past couple of months we have improved in our defending."
