Sad but true reflection of the game. The kicker is we didn't achieve a pot while we had those 4.
Just look over the park, Liverpool 13/14 had the 'fab four' of Sterling, Sturridge, Coutinho and Suarez.
One left the next season to Barca, another the year after to City, another will leave very soon to Barca and another is a broken down bit part player who is getting touted to teams like West Ham and abroad to get his wages off the books and any sort of fee in return.
Similarly, they now have their new 'four superstars' and within a couple of months of them giving them that tag, Coutinho will soon be gone, Mane and Salah i'd be shocked if they are both still there in two years time, Firminho probably will because he's more a system player than individually a great one.
Most clubs have a small window with a group of players to achieve something, if they don't then you will see that group broken up piece by piece, key is always about the timing.
Think both Spurs and the rs focused so much on getting younger players in that they forgot to add the experienced ones, so by the time the younger lads are ready, half of them have become pissed off at lack of success so want to jump ship, and the cycle repeats itself over again.
Same with us, we had a set of 4 potentially brilliant young players at the same time, and some good solid players, but nothing in between, the ready made playewrs at their peak aged 25-29 for example - it was all 20-21 year olds or 30+ year olds really and the in between ages weren't good enough.
