Jack Sullivan has taken to his Twitter account to give his latest update on West Ham's summer transfer business.
Posting about flying out to Andorra to watch the Hammers play Lusitans in the second leg of their Europa League qualifier on Thursday night, Sullivan said: "As I fly out to Andorra tomorrow! A new CB flys (sic) in for a Medical. #COYI"

Before appointing new boss Slaven Bilic, co-owners Gold and Sullivan pledged to 'invest significantly' in the squad.
And so far they have been true to their word with the east Londoners having already signed goalkeeper Darren Randolph and midfielders Dimitri Payet and Pedro Obiang to add to left back Stephen Hendrie - who was signed in January but only officially joined the club on July 1st.
It seems the transfer activity is about to gather pace too with deals for last season's loan stars Alex Song and Carl Jenkinson in the offing, per the Daily Mirror.
Some West Ham fans may see any big money spent on defenders as a waste given that the club is well stocked in that department with established first team players and a crop of talented youngsters emerging from the Academy.
At one stage of West Ham's 3-0 victory over Lusitans last week, their entire back four was made up of Academy players, led by first-team star James Tomkins.
But despite all that Bilic, a former defender himself, has clearly identified it as an area of the team he wants to improve.
The club has been linked with a host of central defenders in the last few weeks so here we take a look at the candidates and who the mystery player could be.
Italy international Angelo Ogbonna is the favourite to be the player referred to by Sullivan junior and the likes of the Guardian have reported he is close to signing from Italian giants Juventus where he has failed to make the grade since signing in 2013.
As a player the 27-year-old has all the attributes to make him a success in the Premier League. Strong and powerful, Ogbonna is known for his outstanding physical attributes and can also play at left back.
He is good with the ball at his feet but interestingly is left footed the same as West Ham's key defender Winston Reid. Of Nigerian heritage, Ogbonna has been likened to Everton's legendary Joseph Yobo.
At 24 he has the potential to go on and prove himself as one of the top defenders in Europe. But the Irons were recently quoted £20 million for the former Basel man, as per the Telegraph, and it remains to be seen whether the club has that kind of spending power.
In January he was linked with a move to Premier League giants Manchester United and Arsenal and would be a serious coup for the club.
He is something of a hot head, though, and famously slapped Swiss politician Ueli Maurer several times on his head during cup final celebrations in 2012 before refusing to apologise only to be forced to by his club later on.
Probably the least likely of the three but if they pull it off arguably the best.
The 25-year-old actually started life as a left-winger but has found his calling as a cultured, tough centre back.
He signed a four-year deal with the French side just last summer so would cost West Ham a pretty penny but he could be the player that turns a good season into a great one, he is that impressive.
