Arsenal picked up a much-needed victory on Monday night beating West Brom 2-0 at the Emirates.
Two goals from Alexandre Lacazette ensured the Gunners move up to seventh place in the Premier League after six games.
But it was far from easy for Arsene Wenger's men. The visitors came close on a number of occasions in the first half and had what seemed a stone wall penalty appeal turned down.
Shkodran Mustafi brought down Jay Rodriguez inside the box, but referee Bobby Madley waved play on.
Lacazette then opened the scoring to put Arsenal in control but had West Brom been given a penalty, the outcome could have been very different.
And according to their manager Tony Pulis, that penalty appeal wasn't the only controversial moment of the game.
In his post-match interview, the travelling manager accused Alexis Sanchez of cheating.
The Gunners winger went down a number of times in the match, and Pulis believes he was playing for freekicks and penalties.
In fact, it took Sanchez just three minutes to hit the deck, winning an early set-piece that the West Brom boss saw as a dive.
"Sanchez falls for the first free-kick, not the one they score off, he should be booked because that's cheating," Pulis said, per the Mirror.
He also had something to say about the penalty that was turned down at the other end, suggesting that if his players were diving a spot-kick may have been given.
"Jay is very, very honest, and doesn't get any reward for being honest."
Even though there's no way the outcome of the game can be changed, Pulis may find some comfort in the fact that Sanchez could be retrospectively banned.
But only if the Football Association agree that he was cheating in Monday's match.
At the start of the season, the FA introduced retrospective action for anyone judged to be faking injury or diving.
A three-man panel reviews video footage of the week's action and if all three unanimously agree that a player has been cheating - action can be taken, even if the referee didn't see it.
And that action is likely to be a two-game ban.
Although it will mean little to Pulis now, Sanchez could still be punished and if he is, he may not push the boundaries again.
