FORMER Premier League ref Mark Clattenburg believes what's said on the pitch should stay on the pitch.

Clattenburg once clashed with ex-Saint Adam Lallana which saw the St Mary's side lodge an official complaint.

His comments come on the back of Bournemouth's Dan Gosling hitting out at Jon Moss after their defeat against Sheffield United last weekend.

Writing in his Daily Mail column, Clattenburg reflected: "I had a similar incident with Adam Lallana when he was playing for Southampton in a match at Everton.

"He was giving me some stick and I probably had reason to send him off, but I chose to try to diffuse the situation by saying to him, 'You're different since you played for England'. 

"He was a nice guy but it was true, he had changed!

"But Adam and Southampton then made a complaint. 

"I was disappointed because I'd tried to manage the situation by having a dialogue and making light of it, and the PGMOL said there was no case to answer.

"Jon Moss has perhaps tried the same with Bournemouth's players and I understand why he did that. For me, it is better than issuing cards for dissent.

"However, it is risky if he has joked about the performance of a team fighting relegation, and that is why Dan Gosling has accused him of making disrespectful comments.

"Saying that, I'm a believer in what is said on the pitch should stay on the pitch. I would have preferred to see Gosling and Moss talk it over in private."
