The former Liverpool defender believes Brendan Rodgers could go with three at the back in future.
The defender has found himself out of the Liverpool first-team so far this season, with Dejan Lovren having been preferred alongside Martin Skrtel.
Despite that lack of game time so far this season, he recently signed a new five-year contract with the Premier League side, with Rodgers electing to name him captain for the recent draw with Bordeaux in the Europa League.
But Lawrenson says he has been left confused by the way the club has treated him, saying Rodgers seems to be making rash decisions at present.
“Am I the only person somewhat confused by what’s happening with Mamadou Sakho?” he told the Liverpool Echo.
“Here was a player who had been bombed from the team completely all season. Yet he has one decent game in a second-string side and one day later he agrees a five-year contract. It does feel as though Brendan Rodgers is making his decisions on the hoof at present.”
Rodgers could go with three at the back
It is widely expected that Sakho will now return to the Liverpool first-team in the Premier League, having featured in the Europa League game last week.
That would mean either Dejan Lovren or Martin Skrtel losing their place, with the former the most likely given the struggles he has endured since moving to Anfield last summer.
There is also the option to go with three at the back as he did last season, and Lawrenson says that might be a good option as it would mean going with two up front.
“Maybe Rodgers is now going to look at Sakho and Skrtel as a partnership, but could he stick with three at the back?” he added.
“That would at least give him the opportunity to play two up front, which could be ideal when Daniel Sturridge returns to presumably partner Christian Benteke.”
