Manchester united chelsea launch new kits for 2018 19 ahead of fa cup final

I think there may be a few issues with your statement!

Firstly, Manchester United and Chelsea are two separate football clubs that compete in the Premier League, not the same team. Therefore, it's unlikely that they would launch a joint kit for the 2018-19 season.

Secondly, the FA Cup Final is a single match played between the winners of the FA Cup semi-finals, which are held in April or May. The 2018-19 FA Cup Final was played on May 18, 2019, between Manchester City and Watford, not Manchester United and Chelsea.

Lastly, kit launches are typically done by individual clubs, not joint teams. Each club usually launches its new kit for the upcoming season in the summer, before the start of the new season.

So, to summarize, there was no joint kit launch between Manchester United and Chelsea ahead of the FA Cup Final in 2019.
