With United struggling for consistency this season, Ole Gunnar Solskjaer has toyed with multiple systems involving differing personnel, and is yet to settle on a preferred line-up.
Cavani was brought in to challenge Martial for the No.9 spot, but the Uruguayan has played a bit-part role since completing his move to Old Trafford on deadline day.
The 33-year-old has shown glimpses of his class so far and bagged his first United goal in the 3-1 win over Everton before the international break.
Cavani also got on the scoresheet for his country in a 3-0 win over Colombia last Friday, but was sent off for a late challenge on Richarlison against Brazil in midweek.
The former Paris Saint-German striker could make his first start for United when they host West Bromich Albion at Old Trafford on Saturday.
Meanwhile, Solskjaer will be sweating over the fitness of Rashford, who was forced to withdraw from the England squad with a shoulder problem, and Martial, who reportedly picked up a minor back problem on France duty.
But when all three are fit and firing, former Red Devils striker Berbatov admitted his ideal front three would consist of Martial and Rashford in the wide positions, with Cavani leading the line.
‘At 33, he’s in great shape and, with young guys around him, he could be lethal for United.
‘Saturday’s home match against struggling West Brom would be a perfect opportunity for Solskjaer to play Cavani in the centre of the United attack.’
