Tradition says that Peter went to Rome around 65 CE and led the church there, as the first bishop of Rome, appointing Linus as his successor prior to his own death. Another early tradition, recorded by the second-century Church Father Irenaeus (Against Heresies, Book III, Chapter 3), says that Peter and Paul together organised the Roman church and jointly appointed Linus as the first in the succession of bishops of Rome, implying that Peter had not yet achieved status in tradition as the sole leader of the church of Rome. According to Irenaeus' account, although Peter might have gone to Rome, it could be risky to attribute to him the traditional role as monepiscopal bishop of Rome.
Francis A. Sullivan says, in From Apostles to Bishops,that there is a general agreement among scholars, including Catholic scholars, that the church of Rome was led by a council of presbyters until well into the second century, with no evidence of a ruling bishop. Although Catholic scholars are bound to regard Peter as the first bishop of Rome and therefore the first pope, this consensus certainly calls into doubt any tradition that includes Linus as one in a continuous line of bishops. In fact, there is no evidence that Peter ever went to Rome, either to lead the church or even as a visiting apostle.
This leaves us with Matthew's attestation that Jesus said, perhaps around 30 CE, he would build his church on this rock (Peter), but without an association with the church in Rome.
