Southampton manager Claude Puel has claimed that inform striker Charlie Austin is not certain to start in the club's Europa League game against Inter Milan on Thursday.
Two goals in the Saints 3-1 win over Burnley on Sunday saw Austin take his tally to seven goals in his last six games, but Puel was determined to stress that he cannot start every game.

Asked whether the 27-year old striker is undroppable, Puel toldSky Sports:"No, it's important he doesn't play all the games from the start.
"It's important you don't lose Charlie, it's important he's available every time, to keep a good physical level for every player.
"Charlie is not an endurance player; it's important to keep him with his qualities, and we can change the team every game. It's not possible, for me, for a player to start all the games every three days.
"We can keep all the players with a good performance all the time, and a good physical level. It's important to conserve [their energy], to continue this work for the team, for the future."
Puel was also queried on any possible England selections for his players in the future, including Nathan Redmond and Austin.
"I would like a selection for all of my players. Many have good qualities," he added.
"Two players, for example, had a good game. I'm happy for [Austin], for us. He likes to score.
"The team plays good football and takes confidence from Charlie's quality. At the moment he's very important and interesting for us."
Southampton's win against Burnley took them up to eighth in the Premier League table.
