Inter head coach Simone Inzaghi believes his team need to play with "aggression and determination" against Barcelona in the Champions League on Tuesday.

Inzaghi is under fire after a run that has seen Inter lose four of their last six in all competitions, with a 2-1 home defeat to Roma at the weekend leaving the Nerazzurri ninth in Serie A, already eight points behind joint-leaders Napoli and Atalanta.

And Tuesday's match will see them host a Barcelona side in red-hot form, top of LaLiga and yet to lose a league match this season under the leadership of former midfielder Xavi.

In his pre-match press conference, Inzaghi outlined just how tough a task the game was going to be, while explaining how his team need to play at the San Siro if they are to get a result.

"Tomorrow is a great opportunity, knowing that we meet a very strong team, probably one of the best in Europe," Inzaghi told reporters.

"It is a complete, strong team with a lot of quality. They know how to do everything, they have pressing and ball recovery. It is a team that knows how to do everything in possession and non-possession.

"Barcelona are a very strong team, complete in all departments. They have a lot of quality, plus they have [Robert] Lewandowski.

"We will have to play a game of aggression and determination."

Inzaghi also had positive news about striker Lautaro Martinez's availability for the fixture, adding: "This morning Lautaro made an exam where no injury was evident.

"He finished the game [against Roma] fatigued, today he will do a partial training and we will see what his condition will be."
