Middlesbrough boss Aitor Karanka admitted after the 2-0 loss at Stoke that the Teesside outfit have lots of problems -- but stressed he would not be quitting.
Boro dropped into the relegation zone as their winless run in the Premier League extended to a 10th match at the bet365 Stadium, slipping down a place to 18th, with Crystal Palace moving up to 17th and three points clear of them after a 2-0 victory at West Brom.
Karanka's men -- the lowest scorers in the division, with just 19 goals -- failed to hit the back of the net for a fourth successive league game, and the Spaniard was left disappointed by their defending for both Stoke goals, netted by Marko Arnautovic in the 29th and 42nd minutes.
