"I'm delighted for the boys," added Robinson. "They were fantastic and what pleased me the most was that we dominated a Premier League team for long periods.
"We scored some unbelievable goals that would have graced any ground in the country.
"When we moved the football quickly we looked a very good side against a team that got out of one of the toughest leagues in Europe last season.
"They were a tough test for us and I'm immensely pleased."
Blackpool boss Ian Holloway had made 10 changes to the side that lost 6-0 at Arsenal on Saturday.
However, Holloway did not attend the match as he was watching a possible transfer target, leaving assistant manager Steve Thompson in charge.
"Obviously you want the gaffer here but circumstances at the moment are that he needs to go and get new players in - and that's why they left me in charge," Thompson told BBC Sport.
