Arsenal suffered a 2-1 defeat to Watford at the Emirates Stadium in North London in the quarter-finals of the FA Cup.
The loss means that there is a very good chance that the Gunners will end up without a trophy this season.
Arsene Wenger’s side are still in the race for the Premier League title, but Leicester City and Tottenham are ahead of them in the table.
A 2-0 home defeat to Barcelona in the first leg of the Champions League last-16 tie means that Arsenal are unlikely to progress to the quarter-finals of Europe’s premier club competition.
The 26-year-old, who can play as a forward or as a winger, did not start the tie against Watford and came on a substitute in the 68th minute.
Back in September of last year, Keys questioned Walcott’s lack of development on his website (click here to read more), and he made a sarcastic comment about the England international when he was coming on as a substitute against Watford.
