London, September 18

Jose Mourinho has warned Arsene Wenger that Chelsea are back in the groove as the Premier League champions look to extend their revival in Saturday’s showdown with London rivals Arsenal.

Mourinho’s side are languishing just above the relegation zone following a miserable run of one win from their first five matches, but the Blues boss is confident his players are beginning to rediscover their swagger after a 4-0 demolition of Maccabi Tel Aviv in midweek. That vibrant opening to their Champions League campaign was a stark contrast to the doom and gloom that surrounded the club after their worst start to a season since 1988.

Already trailing leaders Manchester City by 11 points and fourth placed Arsenal by six, a third successive league defeat this weekend could leave Chelsea’s title defence in tatters. Yet Mourinho expects the challenge of taking on a title rivals will draw a powerful performance from his team against an Arsenal side reeling from their surprise Champions League defeat at Dinamo Zagreb.

“We come with a different feeling. We can wake up with a different state of mind,” Mourinho said. “Saturday is a big match, it’s a great rival. This result can put us in a better situation.” Mourinho has been quick to dismiss claims of a rift with captain John Terry, one of several players dropped for the Maccabi clash. But Mourinho looks an agitated figure at present and locking horns with old rival Wenger is likely to keep him in a waspish mood, especially since he is still smarting from losing to the Arsenal chief for the first time in 14 meetings in Community Shield last month.

Facing Chelsea on the back of a European setback is hardly ideal preparation for Arsenal, who haven’t scored in their last four league meetings with the Blues. However, Gunners forward Theo Walcott is adamant his team will shrug off that setback in time to add to the Mourinho’s problems at Stamford Bridge.

The Gunners have been solid if unspectacular in the league so far and Walcott said: “Everyone will be very disappointed but we need to move on now. We have had setbacks before and have managed to bounce back. We have got a big, important game at the weekend.”

City’s flying start to the season ground to a halt with a 2-1 home defeat against Juventus that continued their lacklustre Champions League record. And Manuel Pellegrini’s team would be wise not to underestimate West Ham, who visit Eastlands on Saturday looking to claim a third famous away win of the season after triumphs at Arsenal and Liverpool. “On one hand it would be a surprise of course if we won because before Juventus, Man City scored 11 goals and didn’t concede, they are cruising,” West Ham manager Slaven Bilic said.

Manchester United, five points behind City in third place, will bid for an uplifting end to a traumatic week when they travel to Southampton on Sunday. Louis van Gaal’s team slumped to a 2-1 Champions League defeat at PSV Eindhoven on Tuesday and to make matters worse England left-back Luke Shaw broke his right leg in two places in a challenge with Hector Moreno.

Newcastle, Sunderland and Stoke the three top tier sides still waiting for a first league win this term aim to end their barren runs against Watford, Bournemouth and Leicester respectively.
