Lazio keeper Muslera welcomes Carrizo competition
"It is really important that we can communicate and I feel better on and off the pitch, which is a big thing."
Despite Lazio's miserable 12th-placed finish last term, Muslera is setting his sights on some ambitious objectives.
"I want to win the Scudetto with Lazio and I think this year we can finish fourth," he insisted.
"We have a very strong group and can make a quick return to the Champions League."
