Ian Whittell in The Times doesn’t agree with you. I wouldn’t qui Go as far as him and I though Forster might have done better with their disallowed effort but he did have two opposition players right in his face with no defenders anywhere to be seen.
“Two first-half goals would have been far more but for a stunning display from the Southampton goalkeeper, Fraser Forster, and an indifferent one from his outfield team-mates.”
”…and nine minutes later he made an equally stunning goalline save to keep out a Rodriguez header”
“…when Rodriguez and Cork scrambled the ball in after another superb Forster save, but VAR ruled it fractionally offside.”
