Liverpool legend Phil Thompson has called on Brendan Rodgers to be more flexible with his tactics following the club's last two defeats in the Premier League.
Rodgers had used a seemingly successful 3-4-2-1 formation during a 14-game unbeaten run, but the Reds have now lost two games in a row to Manchester United and Arsenal.
"The system is okay, but certain teams have sussed it out, and Brendan needs to be brave enough to switch to 4-4-1-1 – or whatever he thinks is best at that moment – to stop these games getting away from them," said Thompson, according to Sky Sports News.
"My biggest concern is that – after 15-20 minutes, if it's not working – it needs to be changed.
"As we seen in the Manchester United and Arsenal games, if you wait to half-time to change a system that is being exploited, then you're liable to fall behind before the break."
The Anfield club currently hold fifth spot in the top flight of English football.
