It will be a tough job given the fact that they have lost Gordon also this window. I think still they got some strong players who can help the team when needed but Dyche also need to use them properly. It will be a tough job for him but I think he will do better job than Frank Lampard and hopefully will get them out of the relegation zone.
Dyche's potential was recognized by the team prior to his signing, which is why he was signed. If he can't outperform Frank Lampard in leading the team out of the relegation zone, he won't be considered for the job in the first place. He simply needs to use the players effectively; I see some good players still on the team who can lead the team to victory after victory until they are no longer in the relegation zone.
