Liverpool defender Andrew Robertson says manager Jurgen Klopp had no option but to play Diogo Jota against Manchester City due to his impressive form in recent games.
Amid a drop in form from Roberto Firmino, Jota has stepped up for the Reds since joining in the summer with seven goals in 11 games.
But instead of playing his tried and trusted 4-3-3 formation at the Etihad, Klopp opted to play Firmino, Jota, Sadio Mane and Mohamed Salah in a 4-2-4 system.
In the opening 20 minutes, Liverpool were the better side and they eventually took the lead when Mane was brought down in the penalty area and Salah scored from the spot.
Gabriel Jesus levelled the match with a smart turn and finish past Alisson and the two sides cancelled settled for a draw in the second half.
It remains to be seen whether Klopp will continue with the quartet of Firmino, Jota, Mane and Salah long term.
But Robertson believes the versatility of the squad is a strength.
Robertson told Liverpoolfc.com: “Look, that's what happens with players like Diogo – who scored a hat-trick in midweek, he's scored so many goals – and obviously the manager looked at it and thought, 'I have to get him in the team'.

“The front three have been phenomenal the last three years and then we bring on quality like Shaq [Xherdan Shaqiri], who is in such a good moment right now.
"He has played phenomenal football the past couple of weeks and then we bring on Millie [James Milner], trusty Millie, slotting in for Trent [Alexander-Arnold].
“That was part of us maybe adapting as a team, being able to play different formations, being able to play different personnel and things like that, and we managed to do that against one of the best teams in the league.
“I thought we did it pretty well and we can adapt, and it means that we can maybe play it more often, but the 4-3-3 has worked so well for us.
"So we won't play it all the time, but it means we can adapt to certain teams, certain situations and it's about us evolving as a team. So that was a big step.”
