No vacation for Salah and Mane that the latest news from them currently they will back to Liverpool immediately and probably both of players will play against Leicester this weekend although i'm sure Salah very disappointed with the result of the african cup but he will be professional because Liverpool upcoming matches very important and they will playing again together to help Liverpool get winnings
Good news for Liverpool if Mohamed Salah and Sadio Mane can be used in the match against Leicester later. We know these two players are contributing players to the team. And also their current opponent, Leicester. Leicester is a team that always surprises big teams. Moreover, in the last meeting, Liverpool had to admit their defeat to Leicester with a score of 1-0. Liverpool must be wary of them if they don't want to be beaten by Leicester at home.
One of the great things about Klopp is that, he doesn't need superstars to actually win a game, he can't win a horrible team of course, but he gets the most out of every player. So, if Mane and Salah weren't available until the end of the season, I am 99% sure that they would finish either second or possible at worst chance third.
They are capable of beating Leicester without having Mane or Salah, or they could lose with them, the results are never really known until played but I am sure that it wasn't because both were lacking. It is of course still better to have good players, and they will get two of their stars back from finals.
