"I think the game should have been finished at half-time for me".
Harry Kane's second-half strike ensured they did so, and Wenger's side are now seven points behind Tottenham in sixth, but the French manager claimed his side should have been ahead by then. We had opportunities, unsafe situations that we didn't transform into opportunities, that's where my regret was.

Wenger admitted that his team's chances of finishing in the top four now look bleak, but refused to give up completely.
Real Madrid v Real Sociedad
However, Real have crumbled this season, crashing out of the Copa del Rey and enduring a miserable domestic campaign. But they have won their last games against Real Sociedad at home easily , and I don't expect that to change.

Putting together back-to-back league wins is proving to be a problem for Spurs at the moment, last doing so at the very start of January, though Pochettino's charges have a favourable run of fixtures to come once they navigate this tricky test against Arsenal.
Pierre-Emerick Aubameyang has scored four goals in four previous appearances against Tottenham Hotspur in all competitions; once in the Champions League (2 games) and three goals in the Europa League (2 games).
"Kane made the difference, that's what he's about", Arsenal manager Arsene Wenger said.
Many have believed Vertonghen to be one of the best defenders in the league, with a number of them feeling he goes under the radar.
