#1 Suso
Liverpool have been linked with a £40m move for Suso for some time now. It's unbelievable to think that four years ago they actually had him in their squad, but sold him off to AC Milan for a mere £1m. The Reds have lived to rue this error ever since.
Suso is a dynamic forward, who tends to be played out on the right-wing, but can also play central when required. This is exactly the type of player that Klopp adores and would use frequently - especially with the way his current side is set up. Like Muniain and Zaha, Suso would become an indispensable member in the Liverpool line-up.
Transfermarkt value Suso at £36m, so a deal worth about £40m in total would be a realistic transfer in January. Also, Suso is still only 25 years old, so has plenty left to offer.
Rumour probability: 8/10
There's no doubt that the Premier League is far more prestigious than Serie A, so the chance to sign with Liverpool would be a very tempting opportunity for the Spaniard. Liverpool are also a much larger club than AC Milan, so playing at Anfield is naturally a better option than the San Siro.
Suso must be eager to finish what he started at Liverpool, so the likelihood of this deal being completed next month is fairly high.
