Jamie Vardy fit to return for Leicester at Chelsea after injury
Carlos Carvalhal is determined to hold onto star defender Alfie Mawson, suggesting Swansea would only consider selling the England Under-21 defender if they received an offer in the region of £50 million.
Mawson has been heavily linked with Watford and West Ham in the January transfer window, while Celtic and Everton are also reportedly interested in the 23-year-old Londoner.
Swansea signed Mawson from Barnsley for £5m in August 2016 and he has two-and-a-half-years left on his contract at the Liberty Stadium.
But Carvalhal insists buying rather than selling is on the agenda of the Premier League's bottom club this month, with the Portuguese saying that chairman Huw Jenkins has given him assurances that Mawson will not be leaving the club.
"When I signed [as manager last month] it was very clear we would try and bring in players to improve the team,'' he said.
"We will not sell the best players in January, the message is clear.
"I have had guarantees from the chairman, but it depends if someone comes in and gives £50m, £100m, £250m.
"Of course, then it is completely different -- to me, [Philippe] Coutinho or Neymar.
"You can never say that it will not happen, but the fundamental idea is not to sell players and try to improve the team.''
Carvalhal used a fishing analogy last week when he suggested Swansea would have to buy "sardines and not lobster'' in January.
If that was a sign that Swansea will not be spending millions in their attempt to escape relegation, Carvalhal said the club have been busy in their pursuit of targets.
Keeping the fishing talk going, he said: "The boat is on the sea -- but the fish didn't bite the hook.
"There is nothing so far, but you never know when the boat is on the sea.
"It depends if you have a storm or whether the fish are sleeping or not if they come to the boat or not.
"I won't talk about numbers but I want quality players. If we bring some quality players in, it will be on our budget.''
Swansea travel to Newcastle on Saturday with doubts over Renato Sanches and Tammy Abraham.
However, South Korea midfielder Ki Sung-yueng could return after a month out with a calf injury.
"The team against Watford, Tottenham and Wolves played like I want at that moment,'' Carvalhal said about his first three games in charge.
"Let's see game by game. It is not just the philosophy, it is trying to achieve points.
"It will not happen in two days or two weeks.
"It might not be possible for the team to play as I want after just a month, what is important is that we fight to win games.''
Leicester striker Jamie Vardy will be fit to face Chelsea after recovering from a groin injury.
The England international missed Saturday's FA Cup draw at former club Fleetwood but will travel to Stamford Bridge on Saturday.
Captain Wes Morgan and defender Danny Simpson remain out with a hamstring problems but Vicente Iborra (hamstring) Christian Fuchs (illness) are available for the Foxes.
Boss Claude Puel said: "He will be available for the game, there is no problem with Jamie. He can train well this week.
"I don't know how long Wes will stay outside the squad but I hope to have some good news and hope I can speak about the end of the injury.
"Simpson can run a little which is good news and we will see when he can come back into the team."
Meanwhile, Puel confirmed the Foxes are close to the signing of Fousseni Diabate from French Ligue 2 club Gazelec Ajaccio.
They have agreed a fee of around £2million for the 22-year-old, who can play either as a striker or a winger.
Puel said: "He is close to signing and it's a good opportunity for us. In the past Leicester haven't signed bad players from Ligue 2, like [Riyad] Mahrez.
"He has quality, pace, penetration and is good with ball at his feet. He can play as a winger wide right or left and striker also.
"He's an interesting player for the future and will be between the Under-23 and Premier League squad -- he has quality to play in Premier League. He's a young player but has all the attributes to become a good player."
