Mauricio Pellegrino has spoken of his trust in new signing Guido Carrillo, after being reunited with the striker at Southampton.
The 26-year-old completed his move to St Mary's from French club AS Monaco on Thursday night, linking up once again with his fellow Argentine, who he worked under at Estudiantes.
"I knew him when he was really young, 19-years-old," said Pellegrino. "It was the beginning of his career then.
"He moved to Monaco and he has been competing in a really good team, in the Champions League, with really good competition, and obviously he has improved a lot, but especially I'm pleased because I trust in him as a person and a human being and a character.
"He will be an important player if everything around him falls into place. Like every single player, everyone needs the context, but I think he can help us to be stronger."
Pellegrino also believes Carrillo could be an ideal fit given the absence of Charlie Austin, who is expected to be out for some time yet.
"We were working really hard and pushing really hard to try to bring in somebody who in this moment can replace Charlie, or this profile of player that we don't have right now," said the Saints boss.
"We expect that maybe Charlie will be out in the next couple of months. We hope that maybe he can come back earlier, but it will be a long period of time in two months with a lot of games in front of us that we have to compete in.
"Guido is someone else who can give a plus with this profile, because he is a big body, he can hold the ball, he is good in the air and I think he can help us."
