Trescothick has filled in as interim for three Tests against Pakistan, and will hand over a team fresh from a convincing 3-0 series win. The pair have been in constant communication since Fleming was appointed as Brendon McCullum’s replacement, with Fleming choosing not to take over immediately after ending his association with IPL franchise Chennai Super Kings earlier this summer.

Trescothick will travel down to Southampton on Sunday to rejoin McCullum, who remains white-ball coach, ahead of the first of three T20Is against Sri Lanka, starting on Tuesday. Fellow assistants Sarah Taylor, Tim Southee and Jeetan Patel will also make the journey and will be joined by Kevin Pietersen, who begins his role as a specialist mentor with England’s white-ball sides. On the playing side, limited-overs skipper Harry Brook, Jordan Cox, Ben Duckett, Jofra Archer, Gus Atkinson and Josh Tongue will also venture south.

Speaking at the conclusion of the series, Trescothick said he was still in the dark about his future with the Test side but reiterated his desire to continue.

“No, not really,” he said when asked if he had an idea of his Test commitments going forward. “I’ve spoken with Rob Key a little bit over the last couple of weeks and had bits of discussions on what might happen.

“I think when Stephen [Fleming]’s over and then they – Rob and Stephen and Brendon – can get together and really sort of thrash out exactly how it’s going to look, then we’ll probably be involved in those sort of conversations afterwards.

“Our immediate plan is obviously then looking at the Sri Lanka series we’re now straight into, with the possibility of going maybe into Pakistan. But I think within the next couple of weeks we’ll know a bit more.

“I love doing both formats. Its been brilliant and [I’m] privileged to be in the position of being assistant coach where you’re on the road because it’s great fun and you’re with the team and you’re working with the best. There’s nothing better than working with your own national country, of course. But we’ll see. We’ll see how it pans out.”

Root was particularly effusive about Trescothick’s impact during the Pakistan series, believing he has done his future prospects as a head coach no harm.

“I think the way that he’s worked with me, the way that he’s worked with the group, has been outstanding,” Root said. “And I hope he takes a lot of confidence from it and if he ever gets the opportunity to be a head coach further down the line, it’s been great for him and he’s done a brilliant job over the course of the three games.”

Though out of his hands, Trescothick hopes there will be English representation around the Test side. Fleming’s appointment continues a familiar trend of overseas coaches, with Peter Moores and Chris Silverwood the only two Englishmen among seven to hold the top job this century.

“As much as we can within the course of coaching systems, you want someone within that that can highlight things that are important with England players and England teams and England series that you play,” said Trescothick. “Because they are different to other countries and unique in their own way.

“We want to try and promote our own from within and get them up to the top because there’s nothing better, I don’t think, than if you can get to that point. It’s not the be all and end all. But, I think, as much as we can have the representation in there, then the better it’ll be.”
