The three transfers of Conor Gallagher, Julian Alvarez and Samu Omorodion, which all involve Atletico Madrid, feel loosely tied together - and until they are finalised there will be caution around them going through.
Representatives of all three players believe their transfers are done.
Alvarez, 24, should join Atletico Madrid from Manchester City for £81.5m.
Gallagher, 24, is already in Spain ahead of his £34m move from Chelsea to Atletico Madrid.
And Atletico Madrid striker Samu Omorodion is expected to complete his £34.5m move to Chelsea after the Olympics men's football gold medal match in Paris this evening.
Although the two deals involving Chelsea are not considered swap deals, if one collapses, the other likely will not go through.
That's why the clubs have stopped short of announcing any agreements with a small percentage of doubt still a cause for a small amount of concern.
