Arsenal are set to welcome back goalkeeper Petr Cech for the Premier League visit of Watford after a month out with a calf injury. The Czech Republic international has not played since the defeat to Swansea City at the start of March after suffering a blow during the game which has forced him to miss the Gunners' last five matches.

Jack Wilshere and Tomas Rosicky have also resumed training following significant spells out of the first team. Wilshere has not played this season after breaking his leg in a training session in August, while knee trouble has restricted Rosicky to just one appearance this term in the FA Cup win over Burnley in January.

Playmaker Santi Cazorla remains at least three weeks away from a return for Arsenal after suffering a setback in his return from knee surgery last December. The Spain international is now nursing a achilles problem which is expected to see his absence slip into a fifth month.

"All of our players have come back [from the international break] ok," the Arsenal boss told reporters, according to The Mirror. "Petr Cech has joined training. The good news is Wilshere and Rosicky are back in full training again. Oxlade-Chamberlain is three to four weeks away. I am cautious with him [Wilshere] now. To be back competitive it will take a few weeks. Of course he will be fit for the Euros and I would like him to be picked.

"Cazorla is starting to run but he is a few weeks away I think. I hope [he can have an impact this season] yes because he has started to run. We have to always be cautious because you never know how he will cope after the training sessions. He has a chance to be completely fit before the end of the season and play competitive football."

Wenger is not certain whether Wilshere will make his return for the Arsenal Under-21s against Blackburn Rovers or Newcastle United in the coming week but is hopeful he will return to competitive action before the end of the season. Roy Hodgson will confirm his 23-man squad for the European Championships on 12 May and Wenger is confident he will be available.

"I don't know [if Wilshere will play for the Under-21s]," he added. "I have to decide what is right for him and I am guided by that. You want your players to compete at the top level. Jack is frustrated enough and it is important for his confidence that he goes to the Euros and it is important for England as well that a player of his quality. If he is completely fit then no [it will not be a gamble]."
