West Ham have been told by Swansea boss Carlos Carvalhal that if they want to land Alfie Mawson this month, they will have to stump up a fee of £50 million.

Carvalhal addressed the media on Thursday ahead of his side’s game at Newcastle this weekend and Mawson was a hot topic.

The Hammers are stated to hold a keen interest in the promising defender, who has been an important for Swansea in the last two seasons. David Moyes is claimed to be an admirer of Mawson’s talents and is keen to bring him to London this month.

Carvalhal, though, has made his stance on the matter abundantly clear, stating that it will take a monumental bid to lure Mawson away. As quoted by Football London, the Swans boss said:

When I signed (as manager last month) it was very clear we would try and bring in players to improve the team. 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 £50million, £100million, £250million.

You can never say that it will not happen, but the fundamental idea is not to sell players and try to improve the team.

West Ham want to solidify their defence in the January transfer window and Mawson was thought to be one of their prime targets. With a price tag such as this, though, it seems a deal is extremely unlikely.
