In this FA Cup game we have Wrexham, who are in incredible form and fighting for a place in the Premier League and on the other side Chelsea, who are favorites, but also have an important match in the Champions League next week. ​Wrexham are on a winning streak and for the first time since 1997 they are at this stage. The fans will be their 12th player. They will rely on physical play and set pieces. Kiefer Moore is their main threat up front. Chelsea manager Liam Rosenier is likely to rest stars like Joao Pedro for Tuesday's Champions League trip to PSG. Romeo Lavia is expected to start for the first time in months. Liam Delap and Andre Santos are likely to get a chance to prove they deserve a place in the elite. If the game is level after 90 minutes, there is no replay. It goes straight to extra time and penalties. This increases Wrexham's chances of giant-killing. If Wrexham held the result goalless until the 30th minute, Chelsea will become more nervous which is their big chance for a sensation.
