Watford manager Javi Gracia believes that Ole Gunnar Solskjaer's success at Manchester United is about more than motivation.

Many have questioned whether Solskjaer, now the club's permanent boss, has the tactical acumen to compete with the league's top managers.

But Gracia believes that his tactical side is overlooked, as many just focus on how he lifted spirits after Jose Mourinho's sacking.

"The good results help you to keep all the good things you have in the moment," Gracia told the Evening Standard.

"But if you don't have a good base of work tactically, from analysing teams and preparing every single game, the atmosphere doesn't win games alone.

"You need to do a lot of things well. After that, the atmosphere is a consequence of the other important things.

"It is not a surprise [how well Solskjaer has done]. He is doing really well changing the team.

"He is getting good results with a good squad. They have a very good squad but to win and to be on the up is not easy for anybody. And in this case he has done a very good job."
