Cesc Fabregas was happy with his comeback from a hamstring injury as Arsenal romped to a 5-1 Champions League win over Shakhtar Donetsk.[LNB] Fabregas played for just over an hour and scored a penalty as the Ukrainians were brushed aside at the Emirates Stadium.[LNB]"I wanted to have 60-70 minutes and at 3-0 it was time to come off," the Spaniard told Sky Sports 2.[LNB]"I didn't feel anything, it felt great. We thought it was better to start the game because mentally you are more ready and you warm up better. It felt fine."[LNB]Arsene Wenger was also pleased with his captain's progress and said: "We were a bit cautious and apprehensive in the decision but the fact he got 60 minutes without injury is very good."[LNB]Arsenal have now scored 14 goals in winning their first three games in Group H, but Wenger added: "Let's not deduce too much, we have shown good quality but it is just the start, let's continue to improve.[LNB]"I am cautious because as soon as you lose urgency your level drops dramatically. The team has good potential, and they have shown that again tonight."[LNB]On Fabregas' midfield colleague Jack Wilshere, who was also among the goals, Wenger said: "His maturity is miles ahead of his age, and that is a sign of his talent.[LNB]"I am happy Jack got a goal because he ran after it for some time."[LNB]Wilshere added: "I've had a lot of games now and scored a couple, hopefully I can get a few more games now."[LNB]On his side's goal glut - which also saw Alexandre Song, Samir Nasri and Marouane Chamakh find the net - the teenager said: "I think it shows we're ready for the competition, even in the Premier League we're scoring goals.[LNB]"We started off sharp, they couldn't handle us and we got the goals."
