Liverpool are now the out-and-out favourites to bring Marco Reus in from Dortmund in January.
The winger signed a new contract with the Bundesliga side earlier in 2015, but he agreed to that deal whilst Jurgen Klopp was still in charge.
The manager has since moved to Liverpool, and he is believed likely to try and raid his former side for the German international.
The Anfield club have not been shy of spending in previous windows, whilst Brendan Rodgers was in charge, but it is unclear how much the German manager will have to spend on tinkering his squad in his first transfer window since moving to Merseyside.
The Reds can be backed at 6/1 to sign Reus before the February 3 deadline with SkyBet, with the next in the betting quoted as Barcelona in at 12/1.
Manchester United and Real Madrid are available at a larger 20/1 to complete a deal during the coming window, although their is no certainty that the winger will leave his current club.
