Jennings confirmed for debut in Mumbai

Alastair Cook has confirmed that Keaton Jennings will make his Test debut in the fourth Test against India in Mumbai on Thursday, but Stuart Broad's foot injury looks increasingly likely to sideline him once again.

Jennings, the South African-born son of coach and former player Ray Jennings, only arrived in Mumbai on Monday having been called up from the England Lions squad in the UAE to replace the injured Haseeb Hameed. He will be Cook's 11th opening partner since the retirement of Andrew Strauss in August 2012.

While Jennings' preparation is not perfect, Cook said he was reminded of his own debut "10 years ago" when he flew into India 48 hours ahead of the game and hit a century in the Nagpur Test of 2006.

Cook also described Broad's chances of playing as 50:50. Broad sustained his foot injury during the Visakhapatnam Test and subsequently missed the game in Mohali. While he bowled in training on Tuesday, the England camp have yet to make a decision over his involvement.

However, Broad took a peripheral part in Wednesday's practice - he was referee in the football match that precedes England's training sessions - and did not bowl. He therefore looks most unlikely to be cleared fit to play on Thursday.

That leaves England with a choice to make over who to play in his place. Liam Dawson provides the all-round option and could come in for his debut, though Jake Ball, the seamer, may have sneaked in front of Steven Finn in the pecking order.

Meanwhile Cook played down any hint of a difference of opinion between himself and the England coach, Trevor Bayliss.

Bayliss has recently stated that he would take more of a vocal role in preparation for the final two Tests of the series to remind England that they play at their best, in his view, when they are attempting to be more positive.

But while that could have been interpreted as a contradiction of Cook's views - Cook had decided England would try to block their way to safety in the fourth innings in Vizag - he insists that is not the case. And while he admitted his own style of batting was less overtly positive than most of his colleagues', he believes there is no clash between his own ethos and that of his coach.

"It was clearly a message I knew was coming out," he said. "We chatted at the end of that game as a leadership group and discussed how we wanted to play and what had happened since our first game when we scored at three-and-a-half runs an over at Rajkot.

"We do have to take the second innings at Vizag out of it because I wonder if there was a hangover from that as we did go back into our shells.

"The clear message is that we want to play a bit more aggressively with positive intent because Trevor likes that and it was the message in his first game with us. Rajkot was our blueprint and we played really well there and hopefully we can go back to that level.

"I think our philosophies are the same. My batting over a long period of time has been about wearing the opposition down and batting for long periods but that doesn't change my intent."

"There are definitely different approaches. It's not just about hitting fours and sixes. It's the intent to score runs and it's a good message we need to keep banging on about."
