Saloman Kalou put the Premier League hosts ahead in the 31st minute but Chelsea were unable to find a second goal. And that failure was punished in the 90th minute when Peter Clarke headed home the equaliser.
Forget the magic of the Cup, beating Crewe next Saturday is far more important for Tilly!
He said after the game: "It's a fantastic day for the club and fans. We had to ride our luck and we got the chance at the death. Our goalkeeper made a great save at the end to keep us in it but the idea was to stay in the game for as long as we could. We had to get a lot of bodies behind the ball and it is not how we normally play. But it worked wonders. But whatever happens, we have had a good cup run. Beating Crewe at home in the league in our next game is more important than Chelsea. We have not worked on the long throws from the right-hand side so that was a bonus. Peter does get in good positions and that is his second goal this season. But on another day we could have lost by four or five goals. If they had scored early on then we would have had to open up and possibly got beaten by a hatful. But it is a great result for us against a team that will finish in the top two of the Premier League I'm sure."
On the West London front Chelsea's striking trio of Joe Cole, Didier Drogba and goalscorer Salomon Kalou cost almost £40million to assemble and yet they squandered another hatful of chances to kill off their lowly opponents.
A disappointed Scolari said: "I need to teach to my players more concentration when they arrive in front of goal. This is my job every day. Maybe it is confidence when they arrive in front of goal, maybe pressure. They need to score more goals and get more confidence. If they are not together, they would not create 15 chances. We played very well and created 15 chances but only one goal. Southend played hard and very spirited for a draw. They got a draw but only had one shot on goal."
Well Phil there was the header that hit the bar but fair play, your the manager under pressure, we understand.
