Ozil treble, Sanchez gem inspire rampant Arsenal

London - Mesut Ozil and Alexis Sanchez showed why their value to Arsenal is priceless as the peerless duo inspired a 6-0 thrashing of Bulgarian minnow Ludogorets in the Champions League on Wednesday.

Gunners boss Arsene Wenger has urged Ozil and Sanchez not to get greedy after reports they both plan to demand Arsenal increase its wages to £250,000-per-week when contract talks are reopened later this month.

Sanchez and Ozil's current deals expire in 2018, but Arsenal want its prize assets to commit their long-term futures to the club and on the evidence of their swaggering displays at the Emirates Stadium, they should pay them whatever they want.

Sanchez was the catalyst for Arsenal's romp as the former Barcelona star netted his sixth goal of the season with a quite brilliant first half chip, while German midfielder Ozil smashed a second half hat-trick.

Theo Walcott and Alex Oxlade-Chamberlain were also on the scoresheet for rampant Arsenal, who is top of Champions League Group A after three matches and well on course for the last 16.

Unbeaten in Europe this season, Arsenal has now won seven successive matches in all competitions.

After scoring twice against Swansea, Walcott had a golden opportunity to extend his hot streak when Sanchez picked him out unmarked inside the penalty area.

With only Ludogorets goalkeeper Vladislav Stoyanov to beat, Walcott strangely opted for a cross and his scuffed delivery was easily cleared.

Walcott's faux pas was never likely to derail Arsenal for long as it cut through the Ludogorets defence time and again before taking the lead in the 12th minute.

Taking possession on the left edge of the Ludogorets penalty area after beating the Bulgarians' attempted offside trap, Sanchez looked up and lofted a majestic chip that arched over Stoyanov before nestling into the far corner.
