Arsenal goalkeeper Petr Cech admits they weren't good enough for defeat at Newcastle United.

Arsenal blew a 1-0 lead to lose 2-1 at Newcastle on Sunday.

Matt Ritchie's 68th-minute goal earned the Magpies their fourth straight league win and put them on 41 points with five games remaining, 13 clear of relegation.

Ayoze Perez had equalised just before the half-hour mark, canceling out Alexandre Lacazette's opener for Arsenal.

Cech said: "At 1-0 up we were in control and doing really well.

"We tried to find an opening and a winning goal but we didn't create enough in second half

"The second goal sums up our away form this season and we made a number of mistakes which led to the goal."
