The Baggies travel to the Emirates Stadium tomorrow in search three points to take them even closer to Premier League survival, but Arsenal can guarantee a top four finish with a win, making the clash in North London important for both sides with the end of the season drawing ever closer.
Since sacking Steve Clarke and appointing Spaniard Pepe Mel, West Brom have been indifferent at best, often throwing away points in the final seconds of games, which has made their position above the relegation zone ever more precarious by the week.
But vital wins over Norwich City and West Ham United in recent weeks have given Albion the boost they needed, and are now four points clear of the drop zone and edging ever closer to survival once again. During the tough times at The Hawthorns, Mel was reportedly under huge amounts of pressure and praised Wenger's tenure at Arsenal before Sunday's meeting.
Yet Mel also added that, had Wenger been managing in Spain, where Mel was with Real Betis most recently, then he would probably have been sacked by now. After all, Arsenal are closing in on nine years without a trophy, and Mel believes it would've been too long for Spanish teams to tolerate.
"I don't think Arsene would have survived in Spain," he said. "Carlo Ancelotti at Real Madrid is a good example. Three months ago he was under real pressure and now they are in the Champions League final.
"In Spain, England and Germany it is always the same, the head coach lives for the results. But I'm not surprised Arsene is still in a job as I agree with Arsenal. He has a good philosophy."
