After a year-long wait, Naby Keita is finally a Liverpool player.
Reds fans rejoiced in seeing their new number 8 in his new colours, adding to the renewed sense of optimism around the club since the Champions League final defeat to Real Madrid.
Conversely, however, the deal has left a bad taste in the mouths of Manchester United supporters, as news broke that Marouane Fellaini had signed a new deal at Old Trafford on the same day.
Fellaini made 23 appearances for the club last season, but some fans couldn't help but draw comparisons between the two stories, and despite United announcing the signing of Brazil midfielder Fred earlier this month, many feel as if their club is being left behind in the transfer market in the wake of Keita's unveiling at their rivals.
Here's what some United fans had to say on Twitter.
Fellaini, 30, signed a two-year contract extension with the Red Devils that will see him stay at the club until 2020.
