The flanker returned a fortnight ago from 10 weeks off after shoulder surgery which forced him to miss the Six Nations and has two games to force his way into the British & Irish Lions squad, which is named on April 19.

Robshaw is nowhere near burned out after his enforced break but thinks plans for an 11-month season from 2020 could leave stars in pieces.
“I have only seen a brief outline but it looks pretty tough,” he said. “Burn-out will occur if you are going to be playing 11 months of the year.
“You look at that World Cup year we had which was over a year and how exhausted everyone was on the back of that. To do that every single year will take a lot out of the guys.

“If it’s going to be like that squads are going to have to be a lot bigger because you’re going to have to rotate a lot. You can’t ask guys to play more games. We’re playing the maximum games we can.
“As a player, you always want to play but every now and then you need it taken out of your hands like when a coach says, ‘you’re being rested’.”
The flanker looked better than ever in his first game back, a 53-17 win for Harlequins over Newcastle, which left his old boss Dean Richards saying Robshaw must tour with the Lions.
Quins have been decimated by injuries this year but the cavalry are returning and Robshaw believes the crowded casualty ward helped his rehabilitation.
“Luckily, not for Quins but for us injured lads, there were quite a few guys injured,” he said. “Normally you’re doing weights on your own but there were groups of us so we had that camaraderie knowing that you’re all in similar times.
