While many big deals have already been completed there remains a very real possibility of transfer merry-go-rounds occurring across Europe over the coming weeks.
For instance, if James Rodriguez joins Real Madrid, then Angel di Maria will likely leave the Estadio Santiago Bernabeu side - perhaps to Arsenal, who were linked with the Argentine last summer.
If that transfer rumour were to bear fruit, then joining Colombian superstar Rodriguez in the Spanish capital could be Toni Kroos who is allegedly Carlo Ancelotti's primary choice for any central midfield acquisition.
Such a move may interest the German despite playing down speculation when asked for comment recently.
He said: "Now's not the time to talk about that sort of thing. My mind is focussed on Germany and the goal of winning the World Cup. I've got a contract with Bayern 'till 2015 and over the last five months I've had plenty of similar situations. When it's not Real, it's United. They're great teams, just as Bayern is. If there's a decision to be made, it'll be after the World Cup".
Regardless, because of that precarious contractual situation and a seemingly refusal to extend his terms with the Allianz Arena side beyond 2015, Kroos could be sold by the behemoth of German football that is Bayern.
Bundesliga football expert Jan Aage Fjortoft believes that if such a transfer were to occur then Liverpool would stand to lose out, as Bayern may be loathe to lose both Kroos and Xherdan Shaqiri in the same window.
Fjortoft said: "Do I think Bayern will let Shaqiri go? Depending on what's happening with Kroos. Will he stay or will he go?
"The fact that Franck Ribery is still injured also makes it more likely that the Swiss has to stay," he concluded.
