Arsenal boss Arsene Wenger is unsure how things will pan out on the touchline tonight against Newcastle United.

Wenger has history of his own with Newcastle counterpart Alan Pardew ahead of tonight's crucial clash.

The Arsenal boss was fined £10,000 by the FA for a touchline confrontation with Pardew in November 2006 after taking exception to the former West Ham chief's goal celebration.

Wenger refused to shake Pardew's hand following that Upton Park defeat and relations between the two men remain strained.

He added: "I don't want to go into my relationship with Pardew. I respect every manager before and after the game but during the match we fight against each other."
