The pitch gets relayed after every season.
Endangering the players?
If there is a fine, it will be nothing compared to what the PL will fine City if they win their case against City, and what City may have to pay other PL clubs in compensation.
You will have noticed yesterday the exact same thing happened as last season.
GMP formed a corden around the West Ham fans. No City fans went near or goaded the West Ham fans. In fact, both sets of fans were celebrating City beating Arsenal to the title.
The stewards all stepped aside on instruction from the club and allowed City fans to get on to the pitch from all 4 stands.
The City fans got on to the pitch, celebrated, and then went back to their seats without causing any trouble.
The PL title winning podium was then set up.
The players lifted the PL trophy.
Pep, the coaching staff, the players and their families did a lap of honour celebrating with the fans who were back on the terraces.
A fantastic day, and a fantastic end to a 4th PL title in a row season.
