England, its host for a majority of the tour, has comprehensively outplayed it in both Tests and ODIs so far, and in doing so, has claimed an unassailable lead in the new multi-format points system. So it is that when the two sides clash one final time in a Twenty20 International at the Rose Bowl in Southampton on Tuesday (July 5), Sri Lanka will be fighting to avoid a clean sweep across formats.

After a 0-2 loss in the Tests and a 0-3 reversal in the ODIs, Sri Lanka will find it a struggle to boost morale. After the final ODI – a comprehensive 122-run loss in Cardiff – Angelo Mathews, the captain, found himself fending off questions about his captaincy, saying: “This is a tough time for me as a captain and for the whole unit. But you can’t run away from it.”

The hope was that the ODIs would help Sri Lanka emerge strong from its troubles in Tests, the hope stemming from the possibility of the shorter format narrowing the gap between the teams. However, England – a markedly different side in limited-overs internationals since Sri Lanka defeated it in the ICC World Cup 2015 – proved too strong once again, and apart from the first ODI which ended in a tie, was comprehensive winner in the remaining three completed matches.

The problem for Sri Lanka has been that its departments have struggled to work in tandem. The batsmen posted 305 for 5 in the fourth ODI, but the bowlers struggled to restrict England to below that score. Then, when England set it 325 to win in the fifth, its batsmen were contained to 202.

“I’m pretty sure if we keep improving day by day, we can come out of this hole,” said Mathews after the final ODI. “For the past two months, we’ve been having the same problems, either batting, bowling or fielding has let us down in every single game.”

Ahead of the final clash of what has been a tiresome series, Sri Lanka will hope to depart with its heads held high. A late cameo or a couple of miscues usually prove decisive in T20s, and Sri Lanka knows it has its best chance yet to put one over England. Recent form doesn’t favour Sri Lanka in that respect either – England reached the final of the ICC World T20 2016, while the Sri Lankans failed to get out of their group.

England, meanwhile, is expected to blood a few youngsters in the one-off clash, including Tymal Mills, the paceman. He comes with a reputation for searing pace, something that gained momentum after he roughed up Chris Gayle during the NatWest T20 blast last month. “I’d love to see him play. I won’t be the sole selector, but from my point of view, it would be great to see someone like that charge and give it everything,” said Trevor Bayliss, the England coach.

“It’s good to see some batsmen ducking and weaving.”

Eoin Morgan, the England captain, spoke before the ODIs of how much of a confidence booster it was for the side to reach the ICC World T20 2016 final, and warned of coping with bigger expectations. Those expectations would only have increased after its performances in the series so far.

Teams (from):

England: Eoin Morgan (capt), Sam Billings, Johnny Bairstow, Jos Buttler, Liam Dawson, Chris Jordan, David Malan, Tymal Mills, Liam Plunkett, Adil Rashid, Jason Roy, James Vince, David Willey.

Sri Lanka: Angelo Mathews (capt), Lahiru Thirimanne, Dinesh Chandimal, Kusal Perera, Danushka Gunathilaka, Upul Tharanga, Dhananjaya de Silva, Nuwan Pradeep, Suranga Lakmal, Kusal Mendis, Dasun Shanaka, Farveez Maharoof, Suraj Randiv, Seekkuge Prasanna.

Sri Lanka are rebuilding following the retirement of their batting greats, Mahela Jayawardena and Kumar Sangakkara, within the space of a year.

The West Indies, already hit by the reluctance of senior pros like Chris Gayle and Dwayne Bravo to play Test cricket, faced further turmoil when coach Phil Simmons was stood down for the tour for speaking out against his board’s selection policies.

Former fast bowler and selector Eldine Baptiste, who will serve as interim coach for the tour, will try to ease newly-appointed Test captain Jason Holder into the role.

Holder, a 23-year-old all-rounder who has played just eight Tests, was a surprise choice to replace the seasoned Denesh Ramdin as captain.

“We have a very young team and a young captain,” Baptiste said. “My job is to keep the team focused for the Test matches.”

The West Indies are searching for their maiden Test win on Sri Lankan soil, where they have played nine matches since 1993 — losing five and drawing the other four.

Both teams will look to bounce back after a lacklustre year.

The West Indians lost to South Africa and Australia, while the home series against England was drawn 1-1.

Angelo Mathews’ Sri Lanka crashed to a 2-0 series defeat in New Zealand and lost home series to Pakistan and India by identical 2-1 margins.

Like their rivals, Sri Lanka too have an interim coach in Jerome Jayaratne, who was given charge of the team after Marvan Atapattu resigned in the wake of the defeat against India.

Jayaratne, who did not play international cricket but made his mark as head of the Sri Lankan board’s coaching department, has already described Mathews’ boys as the “worst fielding side in Asia”.

He refused to take victory for granted against the young touring side.

“I would like to believe that we have a better chance of getting back to winning ways, but I definitely won’t underestimate them,” he said.

Only two players from either side have played more than 50 Tests — Mathews and Rangana Herath for Sri Lanka and batsman Marlon Samuels and Ramdin for the West Indies.

Herath, the 37-year-old left-arm spinner, could prove to be the difference when the first Test starts at the picturesque Galle International Stadium, a venue that traditionally favours spin.

Herath took seven for 48 against India in August, helping Sri Lanka bounce back to win that Test by 63 runs.

In June Pakistani spin twins Yasir Shar and Zulfiqar Babar combined to grab 13 wickets between them as Sri Lanka suffered a 10-wicket defeat at the same venue.

In the absence of star spinner Sunil Narine, who was not picked for the Tests, the West Indies will rely on leg-break bowler Devendra Bishoo, who has claimed 50 wickets in 13 Tests so far.

Sri Lanka’s batting in the absence of Jayawardene and Sangakkara will revolve around skipper Mathews, who hit three centuries in the home Tests against Pakistan and India.
