Leon Britton urges Swansea not to sell Ashley Williams

Swansea City midfielder Leon Britton says it is crucial that the club keep captain Ashley Williams this summer.

Williams, who has impressed during Swansea's Premier League campaign, has been linked with a move to Arsenal and Liverpool.

The 28-year-old signed a new three-year contract with the Swans in October.

"It is vitally important that we keep someone like Ashley. He has been fantastic since he joined us and he is the captain now," said Britton.

"He has been absolutely brilliant, and it's no surprise he has been linked with Liverpool and Arsenal.

"It is a testament to the player because he has been outstanding, but hopefully we can keep hold of him.

"We would all love him to stay and we will see what the summer holds but hopefully come the start of August he will still be here."

Williams, who is under contract until 2015, played an influential role as Swansea enjoyed a historic season, finishing ninth in the Premier League and lifting their first major trophy by beating Bradford City 5-0 to win the League Cup.

The Swans' victory at Wembley means they will play in Europe next season.

Britton admits the Swans need to strengthen their squad in the summer as they prepare to play in the Europa League for the first time.

"I think it is important we spread the games around the squad," said the 30-year-old.

"We have seen this season with the likes of Newcastle and Stoke - two teams who have done well in the Europa League - that you can struggle a bit in the league.

"It can take its toll, but I am sure the management and staff have plans in place to bring players in."
