I have a problem in tournament vs attack

In the tournament I started a match  and I played a vs attack game against the opponent and i was sent to a full match  and i scored 6 goals … and the were recoded in my opponent’s team  because i was not playing withi my team …i was playing against my team using my opponent’s team 🤦🏾‍♂️🙇🏾 

now we are about to loose the league tournament 

Look at that guys total number of goals and look my screenshots showing his stat they are not equal
