Swansea City today announced that they have agreed a fee for Barnsley defender, Alfie Mawson.

While they described the fee as undisclosed, reports suggest that it is one worth £5 million.

Without trying to put too much pressure on the promising 22-year-old, he will fill the void left by the man formerly know as Mr. Swansea - Ashley Williams having departed for Everton this summer in a deal worth £12 million.

And if Barnsley's past exports are anything to go by - John Stones, recently signed by Manchester City for £50 million, and the upcoming Mason Holgate, now at Everton - Mawson will be a terrific addition to the South Wales outfit.

Competition aplenty

While there is still plenty to get through before the deal is complete - a medical to complete, personal terms to agree - Mawson will bring brilliant competition to the heart of defence at the Liberty Stadium.

Francesco Guidolin has already recruited Mike van der Hoorn this summer, and adding the Barnsley defender to his squad would mean that the sold on Williams and loaned out Kyle Bartley are replaced.

That would leave him with four senior centre-backs to choose from once again come the close of the window; with Federico Fernandez and Jordi Amat also already on the books.

Add to this the fact that there are four senior goalkeepers on Guidolin's hands, healthy competition at left-back between Neil Taylor and Stephen Kingsley, and at right-back between Angel Rangel and Kyle Naughton, and Swansea should be set for a season with plenty of clean sheets.

Any more signings?

As the transfer window nears it's conclusion, Swansea's squad is nearing it's completion.

The addition of Mawson could be the penultimate piece in the puzzle, with the centre-forward position the only one lacking the same amount of depth as everywhere else on the pitch now.

With Marvin Emnes likely to leave but out of favour anyway, the Swans only have summer recruits Fernando Llorente and Borja Baston - the latter injured - in this area of the park.

Now, Guidolin has to decide whether or not young Oli McBurnie is capable of competing for a place here after a string of impressive performances, or whether he needs to bring somebody else in instead.
