Arsenal seek top-four spark against West Brom

Sunday's 1-1 draw at home to Crystal Palace saw Arsene Wenger's side slip to fourth place and left them with precious little wriggle room ahead of their final five matches of the season.

Fifth-place Manchester United and sixth-place West Ham United both have opportunities to close the gap on Arsenal on Wednesday and goalkeeper Petr Cech knows that his side cannot afford to keep tossing away points.

"We've been talking about the situation where if any of the teams ahead of us slip, we need to get three points, but unfortunately we've not been able to do that," the Czech international said this week.

"It's disappointing. We were ready to push on, we tried to win all our games and we will try to win all the remaining games, too.

"Other teams are coming very close now and there will be an interesting fight until the end of the season. Let's see if winning all our games is going to be enough to get higher up in the table."

Arsenal dominated Sunday's game against Palace, enjoying 72 percent of possession, but Yannick Bolasie's 81st-minute equaliser allowed the visitors to depart with a share of the points.

Usually ruthless against weaker teams at the Emirates, Arsenal have taken just eight points from a possible 18 in their last six home fixtures and it is threatening to derail their season.

Wenger has never failed to steer Arsenal into the Champions League during his 20-year tenure, but the risk of failure has scarcely loomed so large at this stage of the season.

Arsenal were top of the league as recently as mid-January, but their springtime domestic capitulation, coupled with cup disappointments, has placed the manager in the spotlight as never before.

- 'You shouldn't be nervous' -

With large sections of Arsenal's support now calling on Wenger to step down, another slip-up against West Brom could make for a very uncomfortable evening for the 66-year-old Frenchman.

West Brom, who prevailed 2-1 in November's reverse fixture, would appear to pose little threat to Arsenal's top-four hopes, particularly after a run of four matches without victory.

But with Premier League survival effectively assured, they can play with relative freedom and manager Tony Pulis has urged his players to make the most of successive away games against Arsenal and Tottenham Hotspur.

"They are great games," said Pulis, who saw Saido Berahino have two penalties saved in Saturday's 1-0 home defeat by Watford, which left West Brom 10 points clear of the relegation zone.

"I've told the players when we played Manchester City, there's such a small percentage of people that get the opportunity to do this in their lives.

"We get to go to these football grounds and play against great players, great football teams, at great stadiums. You relish it, you shouldn't be nervous or worried about it.

"We've got the points to keep us in the Premier League, so we should really look forward to these games."

England midfielder Jack Wilshere is nearing a first-team return for Arsenal after stepping up his comeback from a broken fibula with two run-outs for the club's under-21 side.

His midfield colleague Aaron Ramsey is a potential starter against West Brom after making his return from a thigh injury as a late replacement for Alex Iwobi against Palace.

Scottish midfielder James Morrison is a major doubt for West Brom with a hamstring injury, while left-back Chris Brunt (knee ligaments) is a long-term absentee.
