Serge Aurier's first goal for the Club and Heung-Min Son's fourth in as many games secured a 2-0 win and back-to-back victories in the Premier League at Wembley after Stoke were beaten 5-1 on Saturday.
It was hard work against a well-drilled Brighton defensive display that often saw 10 men behind the ball.
We chalked up 25 efforts at goal to Brighton's seven and enjoyed over 75 per cent of possession.
However, clear-cut chances were at a premium against the visitors' packed rearguard. Harry Kane had an effort cleared off the line in the first with Erik Lamela - his first start for almost 14 months - and Sonny also close before Serge's cross sailed into the far corner to hand us the lead on 40 minutes.
