AS Roma chief Walter Sabatini admits they're furious with the Argentine FA over the injury concerns of Erik Lamela.

Lamela arrived injured after being involved in Argentina's U20 World Cup campaign.

Sabatini explained: "For Lamela we have a problem and, hopefully, what I say will be a sort of complaint, but he wrongly participated in the Under-20 World Cup.

"He was injured, at least he could start [games] but then played when injured and has paid a very high price, and I must say, Roma is paying too.

"I am very worried by this story, because I had asked the Argentina Football Federation not to play him, but instead, the boy was sent into the field injured, and is now struggling to return to an acceptable condition, the injured ankle is ailing.

"We are not very happy about this situation. It is one that sees us suffer a lot, but above all, sees the boy penalised."

The sporting director was then asked about the possibility of seeking compensation, something he refused to rule out.

"I must say that when you are working with the Argentine Federation, they ask for an advanced payment of taxes. We've already done that, but we do not yet have the player.

"Frankly, my pain is addressed, more than anything, for the boy, because he would have been able to play a lot sooner.

"He is now struggling a little in understanding stages of game situations and the demands of the Coach. Now, he is still on the margins, he is only 19, so there is hope, of course."
