Klopp's headache, who will replace Mac Allister against Brentford?

During the last Premier League game, where Liverpool drew away at Kenilworth Road against Luton, the Reds were able to rescue a last minute equaliser thanks to Luis Diaz in stoppage time, however in the 54th minute of the second half, the Argentine Alexis Mac Allister was cautioned, receiving his fifth caution and will miss the Reds' next game.

The level shown so far by Alexis Mac Allister has been fundamental to the good performance both in Liverpool and in his national team, and after each game Alexis looks a better performance, as the Argentine has found in the Hungarian Dominik Szoboszlai a great complement to give great balance to the team, so the Argentine is already an indispensable for Klopp. 
So it will be a difficult decision for Klopp to find the right replacement, as a constant that has marked the Reds' season are injuries, and in the last Europa League match, both Curtis Jones and Ryan Gravenberch, were not in the squad to face the game, and are still in doubt for the next game, complicating the situation. 

 
The only players available to play in midfield would be Wataru Endo, Dominik Szoboszlai and Harvey Elliott, who would be in charge of the midfield against Brentford, which will undoubtedly be an important gamble for Klopp, who will have to think very carefully about his strategy. 

A major challenge for Klopp 

After the defeat in France against Toulouse, Jürgen Klopp will have to do a great planning to find solutions, because with the absence of injured players and doubts, he will have to make a great strategy to not give in to adversity, also the team has two consecutive games without a win, so the match against Brentford will be very interesting.
