Sebastian Polter reckons he got through 20 miles-plus in the last ​three games of which​ two miles w​ere​ flat-out sprinting - but insists it’s not enough.

The current Rs system deploys the hitman as the lone Ranger required to belt down either channel, collect, go alone, or wait for reinforcements.

The ‘rest’ he had at Leeds ​in the 1-1 draw ​​lasted all of 24 minutes before he was called to replace the stricken Jamie Mackie.

After he got through another exhausting 90-plus minutes against Charlton on Saturday, the forward believes a proper pre-season will see him even fitter next term.

“The gaffer and (assistant) David Oldfield push me hard to always make a good training so I can be ready so I can play my game,” Polter explained.

“I know I can do more, and during pre-season I will get even fitter. You can always be fitter.

“I played in all the games last week, but I want to.”

Polter admits his own​ domestic league ​in Germany ​doesn't always demand the same slog - but the player signed from FSV Mainz 05 last summer is ​happier​ in the Championship.

“Sometimes in the Bundesliga you don’t have to run as much,” he said. “You just stay your position, and tactics and techniques are more important.

“I think it takes time to come to a new country. I had a bad time at the beginning, but we don’t have to talk about that. The Championship is physical - but I am physical.”

However, Polter believes merely putting in the miles doesn’t cut it.

He added: “For each game it’s always between 10-11k running for me and between 800-1,000m intensity.

“But just because you do the running you’re not going to score a hat-trick. It’s about making the right runs at the right time.”
