Arsenal boss Arsene Wenger says he is impressed with the fitness of new signing Alexis Sanchez.
The praise for the Chilean came in light of the fact the World Cup star had only taken two training sessions with his new teammates before the Emirates Cup
Wenger told Arsenal.com on Monday: "Alexis was quite sharp - one of the sharpest because he was mobile and he made some good runs."
This comes on the back of Olivier Giroud's fitness being criticised as 'not ready' for the weekend game, having had a week less rest than Sanchez, and German World Cup star Lukas Podolski still yet to return.
Yaya Sanogo hit four at the weekend and could be a surprise selection for the home fixture against Crystal Palace if Olivier Giroud does not get up to speed.
Sanchez meanwhile has the added bonus of being able to play out wide or centrally, and with Theo Walcott still in 'light training', there is one less competitor for a starting spot in the first week of the season.
Wenger qualified his comments by suggesting Sanchez still has a little work to do, but his overall first impression - and the fact he played the Chilean for both matches at the weekend, suggest he is more than happy with the condition of his new signing.
Chile's early World Cup elimination at the hands of Brazil in the second round appears to have worked in their favour, unlike Germany's success, and Sanchez if he continues can expect to feature from the start in the opener.
The 25-year-old was pictured a fortnight before his comeback going for a run in his hometown, and that hard work during his 'holiday' time appears to have paid off.
