Autumn international: Italy v Argentina preview

Italian-born Allan, who has made substitute appearances for the Azzurri after being drafted into the squad last month, is one of three changes for the clash against the Pumas at Rome's Olympic Stadium.

The 20-year-old Perpignan wing replaces Luciano Orquera, who drops to the bench, with Michele Campagnaro starting at outside centre in place of veteran Gonzalo Canale.

Canale moves to inside centre to replace Luca Morisi, who has been sidelined since last week having suffered a heavy tackle early in a 37-31 win over Fiji which required him to have his spleen removed.

Robert Barbieri comes back into Brunel's starting XV at openside flanker, replacing Mauro Bergamasco who is not included in the matchday squad.

Both No 8 and captain Sergio Parisse and prop Martin Castrogiovanni will start, meaning the pair will pick up their 101st caps for Italy to pull level with retired scrum-half Alessandro Troncon.

Retired prop Andrea Lo Cicero holds the record for Italy's most caps on 103.

Argentina, meanwhile, have made some changes in personnel and some positional to the team thumped 40-6 by Six Nations champions Wales last weekend.

The Pumas will be without first-choice centres Marcelo Bosch and Santiago Fernandez and lock Patricio Albacete due to an agreement between their European clubs and Argentina.

Coach Daniel Hourcade has moved left wing Horacio Agulla into Bosch's outside centre position in the team he named on Thursday, the Argentine union UAR said in a statement.

Hourcade has brought Lucas Gonzalez Amorosino back into the side on the right wing while Gabriel Azcarate takes the inside centre berth left vacant by Fernandez to make up an untested midfield partnership with Agulla.

Imhoff fit

Juan Imhoff, injured in Argentina's 31-12 defeat by England two weeks ago, returns to the left wing with Santiago Cordero, who made his first Pumas start against the Welsh, stepping back down to the bench.

Bosch has returned to Saracens and Fernandez to Bayonne in France, while in the forwards, lock Mariano Galarza comes in for Albacate, who has gone back to Toulouse.

In the back row, Benjamin Macome comes in at No 8 with Pablo Matera dropping down to the bench and captain Juan Manuel Leguizamon moving to blindside flanker.
