Australia coach Darren Lehmann has denied thinking about bringing in re-enforcements, saying that the same group of players who lost at Lord's by 347 runs will be in contention for the third Test at Old Trafford.

It has been suggested in some circles that veteran former Australia batsman Simon Katich should be called up, given his prolific form at Lancashire, but Lehmann has said this is not an option, despite his top six failing to score many runs.

Lehmann, when asked about brining in outside players, said: "No. (But) we've certainly got to bat better - we know that. 55 overs in the first innings is not acceptable for this group so we've got to get better at batting, full-stop.

The coach denied the idea that his batting woes were due to technical faults, or even that the players just weren't good enough, saying it was more a mental block with the top order. As it was, the tail enders wound up doing the bowling as well as the batting.

He said: "It's probably more of a mental thing to be perfectly honest. We have to make sure they're ready to go and refresh as best we can. We'll have a good time down in Sussex and make sure we play some decent cricket, and last a lot longer than 90 overs if that's possible. That's the key for us.

"As a group we know we've got to play better. Simple. We were outplayed this game and I felt sorry for the bowlers as a team. They only got three-and-a-half hours off I think it was so the batters know we have to contribute the whole time. Top seven, the bottom order needs a bit of a rest before they go and bat."

The Aussies next face Sussex at Hove, and Lehmann said spinner Ashton Agar would be rested as he had a sore hip. This seemed to hint that Nathan Lyon would get his place back in the third Test, after Agar displaced him in the first two games.

Boof added: "Ashton's a bit sore so I don't think he'll play at Sussex - Nathan will play obviously. And then again we have to look at the wicket. History shows it spins a bit and reverses so maybe two spinners. I don't know - we'll have to look at that when we get to Manchester.

"That's what happens when you have two losses you have to keep everything open. As selectors, we will have to speak about it and see where we go from there.

"We're going forward. We obviously need to make more runs. We've bowled really well in the Test matches barring probably Saturday afternoon where they got 150 odd or 160. But I can understand that to be perfectly honest considering how much they've bowled.

"I think the bowlers have only had one day off to be fair. So bowling's fine we've just got to get batting right but we're all going in the right direction so that's a pleasing thing and we've got to stick together as best we can."

"Michael Clarke and Usman Khawaja batted well but they need to make 100s when they get in that position - just like young Joe Root did. Certainly batters at the domestic level have to make 100s and force their way into the side I think.

"If we get the mental side of it right, we'll start to bat better and get some results. We've bowled, as I've said before, really well, so we can't worry about what anyone else says. We accept the criticism and we deserve the criticism to be fair - but we're going in the right direction."
