The Brazilian fired against the upright in the final minute of the first half with us 1-0 up and piling on the pressure.
Gylfi Sigurdsson opened the scoring in the 19th minute after fine work from Christian Eriksen and Roberto Soldado and then Paulinho looked set to tap home Roberto’s cross only for Branislav Ivanovic to slide the ball away.
Chelsea hit back after the break and Hugo Lloris had already saved well from Fernando Torres when John Terry glanced home Juan Mata’s free-kick for 1-1.
Hugo saved well from Andre Schurrle but then Torres was sent off after receiving a second yellow card and we pushed Chelsea back in the final 10 minutes, Gylfi closest to a winner with a volley that dipped just wide.
“I think the decisive moment in the end is Paulinho hitting the post just before half-time,” said Andre.
“If that had gone in it could have put us in a good position and we deserved that for the first half we played.
“The second half wasn’t really well played by both teams. I think Chelsea had the upper hand on the counter attack, looked strong and deserved to get the equaliser from the set-play.
“The result serves them better, for sure. It keeps us near the top, and that’s what we wanted. It’s not a bad result, just a pity our second half wasn’t as good as the first.
“It was a hard battle, both teams wanted to win and a fair result.”
