Southampton No2 Jesus Perez refused to comment on their blow up with ref Mark Clattenburg yesterday.

Perez spoke to the press on the day it was revealed the club has complained to the Professional Game Match Officials Ltd board regarding an alleged insult towards Adam Lallana by referee Mark Clattenburg.

"Our way always is when the game is over, it's time to think about the next game," said Perez.

"So our full focus is to prepare well for the next game, then to ensure we're in best condition for the next match.

"That's our style since we came to England.

"When you are in this business you have to be aware everything is possible.

"We're in the best league, the best environment, in terms of business and media, so we have to respect everything because everyone is proud of this business.

"So it's not difficult for us: we focus and we put our players away from the problems and just think about the football."
