The Blues have enjoyed some spectacular results lately but Adam Bate thinks that run will come to an end against Arsene Wenger\'s side this weekend at the Emirates.It’s been a marvellous week for Chelsea as Roberto Di Matteo continues to oversee an astonishing turnaround in fortunes at Stamford Bridge.After a 5-1 thumping of Tottenham at Wembley on Sunday to reach the FA Cup final, the Blues raised eyebrows around Europe as they beat Barcelona at the Bridge on Wednesday.Chelsea are 28/11 (3.55) with 188Bet to make it a remarkable hat-trick of high-profile wins by beating Arsenal in the early kick-off at the Emirates Stadium on Saturday.The Gunners will be smarting after their shock home defeat to relegation-battlers Wigan on Monday.That loss was an unexpected one given the form of Arsene Wenger’s side in recent months.Nine wins in 10 Premier League games prior to Monday evening has taken Arsenal five points of fourth-placed Spurs.Arsenal are 22/23 (1.96) to return to winning ways here and strengthen their grip on a Champions League spot. The draw is available at 9/4 (3.25).In the other markets, it seems sensible to assume there will be goals in this one. The first game between the sides was a thriller with Arsenal running out 5-3 winners at Chelsea in October.The pick of the bets here is to back over 2.5 goals at 10/11 (1.91) with 188Bet.If you favour Chelsea in this one, there is one scoreline that leaps out.Arsenal have had five 2-1 defeats in the Premier League this season and the Blues have won five games by the same margin.Chelsea can be backed to win 2-1 at a chunky 12/1 (13.0) with 188Bet.But the value, despite the recent form of the visitors, is to back a home win on Saturday.In particular, consider the fact that Chelsea could be fatigued after their efforts and that Arsenal are averaging 1.5 goals in the first-half of each of their last six home games. Arsenal are 17/10 (2.7) to lead at half-time.But with Barcelona awaiting them in midweek, Chelsea are unlikely to have the energy to come back. It is worthwhile taking the industry-best price of 23/10 (3.3) with 188Bet for Arsenal to lead at half-time and go on to win the game.
