Makeweight, incentive, cash-plus-player trade—call it what you will, the football swap deal is alive and kicking.
In the past, we've seen some interesting two-way transfers. Think Samuel Eto'o, who was traded (along with a sackload of Euros) from Barcelona in return for Inter Milan's Zlatan Ibrahimovic. It was a canny move by Inter, who enjoyed a hefty payday and won the treble with the Cameroonian striker.
Or Andy Cole, who was traded in by Newcastle for Manchester United's Keith Gillespie, plus £6 million, in 1995.
Clarence Seedorf, Fabio Cannavaro, Ashley Cole and er...Egil Ostenstad—these players have all been involved in swap deals at some point in their careers.
But who could be involved in such a move before the January window shuts? Over the following slides, you'll find 15 examples.
We think they could all work, no matter how unlikely the moves actually are. Ranked from 15-1, we count down to those who make the most sense.
