Udinese are thrilled with the form being shown by Alexis Sanchez while on-loan at River Plate.

Udinese supremo Franco Soldati said: "The boy is justifying the investment we made to take him, we are calm about this. He's very young and can still do a lot more, his value is worth about £15 million.

"In June he could return to Udine, but we will not exclude anything and first we want to talk about him with River Plate.

"It's normal that such a talent will interest clubs, but for the moment there are no other offers."
