Double delight: Thierry Henry celebrates with Daniel Alves after one of his two goals against Valencia
The Frenchman came off the bench to score the equaliser in a 2-2 draw against Valencia on Saturday and he believes the way the Spanish League leaders fought their way back into the game bodes well for the double header against Chelsea.

He said: 'We showed what courage we have as a side. That was the type of performance that wins you trophies. We lost our concentration twice and they made us pay but we are a brave eam and we came back into the game. Now all our attention turns to Chelsea, Real Madrid and then Chelsea again.'
Those three massive matches are squeezed into eight days in what coach Pep Guardiola is calling the week that will decide the club's season.
And the Barcelona coach said: 'It is the most important week of the year. We are playing for the league and for the Champions League. Now we have to rest and see as many Chelsea games as possible.'
The Spanish side's midfielder, Seydou Keita, suggested Barca's usual attacking style would be reined in to prevent Chelsea from grabbing an away goal.
He said: 'It is very important to win the home leg and keep a clean sheet. Chelsea are rivals that we have studied. We have watched them in the Premier League and the Champions League. We know how physically strong they are and they have playerswho can score goals from nothing.'
Barcelona will be at full-strength for the first leg with only long-term defensive absentee Gabi Milito missing.
UEFA yesterday appointed Wolfgang Stark as the referee for the match in the Camp Nou.
Barcelona will know not to take Mr Stark lightly, the German having sent off two of their players in a Champions League tie with Celtic five years ago.
