The 23-year-old could become a key man for England over the next few years after starring for Roy Hodgson's side.
Jonjo Shelvey's impressive second match for England at the weekend, alongside his solid form for Swansea City over the last two seasons, has marked him out as one of the most exciting central midfielders in English football - so should Liverpool regret selling the 23-year-old, or even consider returning for the ex Charlton academy graduate in the future?
Of course, the match was only against San Marino, but it was another footnote in Shelvey's ascension towards establishing himself at the top level of the game.
Shelvey moved to Merseyside in 2010, and quickly managed to get appearances under his belt, but it was clear that the midfielder would not easily break into the Reds' first team with Steven Gerrard the undisputed man in that role.
When he switched to Swansea in the summer of 2013, Brendan Rodgers had a surplus of central and attacking midfielders. They had just signed Luis Alberto from Sevilla, a move that has so far failed to yield much despite a loan return to La Liga last season.
With Coutinho rising to prominence after his arrival a few months earlier, it was clear that the club were struggling to find room for Shelvey to feature in anything but substitute performances and Europa League matches.
However, Liverpool could never have predicted they would be entering a season without the services of legend Gerrard just two years later in 2015/16, a player who was the most formidable of obstacles to Shelvey's first team football at Anfield.
And with the Reds having recruited three central midfielders since Shelvey departed, and having been linked with a wide number of other options in that position this summer, it is clear Brendan Rodgers has been looking into methods to replace the drive and creativity from the centre of the park now Gerrard has left.
In bringing in James Milner, the Reds have arguably got as good a player as they could have hoped for in that regard, while in all honesty Jordan Henderson had already taken over much of Gerrard's dynamic midfield work since improving drastically in the last two or three years. Milner is 29 though, and may well need replacing in the next three or four seasons.
Shelvey has also come on in leaps and bounds since heading to South Wales, and it's hard to imagine he wouldn't have found a role in this new Liverpool side that Rodgers was assembling. His excellent passing can be utilised further up the pitch, while he has the eye and capability of extraordinary long range strikes as well. Importantly, he has also managed to get a handle on the rashness that at times has flared up during his career.
Though of course the gift of hindsight is a wonderful thing, Liverpool knew that selling Shelvey rather than looking to loan him would be a risk considering his promise. It's impossible to predict whether the England international would have developed to the extent he has if only on loan at the Liberty Stadium, but with the Swans themselves becoming a force in the Premier League it is likely any side that would want to sign the player would have to pay around the £20 million mark if they wanted to try and convince Huw Jenkins to sell.
But let us know what you think - as Liverpool fans do you wish the club had found a way to hang on to Shelvey, or were they right to sell him when they did?
