FRANK Lampard believes he knows what Saints boss Ralph Hasenhuttl is going through.

The Derby County manager took charge of the Championship club in the summer and will host Hasenhuttl’s side in the FA Cup third round today.

And the former England icon understands the selection dilemma Saints’ Austrian chief will be faced with at Pride Park this afternoon.

Lampard said: “Does he change a lot of players to protect that and keep players fresh or does he install a mentality of winning in the way they play and performance that he wants to carry through?

“He’ll have lots of messages that he wants to give the team, I know that because I’m still pretty new here. 

“He may go either way. He may want to rest players or may want to play players who have been playing regularly.

“Whatever way he does it, this is a Premier League squad that we are coming up against so whoever they put out it will be a very tough game for us.”

Derby are currently fighting for a play-off spot in the Championship, but Lampard is adamant they’ll be taking the FA Cup seriously.

They’ve already enjoyed Carabao Cup success this season by knocking out Manchester United before giving Chelsea a run for their money.

“In my opinion you cannot turn off a desire to win games and you are professional,” Lampard added.

“Whether you change the team, and we were fortunate at Chelsea that we had a strong squad and could handle the change in certain games, but in terms of intention and mindset we went into every game to win and that must be the same for us here.

“We showed that attitude in the Carabao Cup and we had a great run in that. 

“Manchester United was one of the best games in recent seasons and we have to try and start out on another journey but we know it will be tough.

“It’s after a busy patch of games and we have suffered some injuries so we will see how we go but the players on the pitch will give everything.”
